Constructor Detail

def self.new(raw : Type) #

Creates a Log::Metadata::Value that wraps the given Type.


[View source]
def self.new(hash : NamedTuple | Hash) #

Creates Log::Metadata from the given values. All keys are converted to String

Instance Method Detail

def ==(other : self) #

Returns true if both self and other's raw object are equal.


[View source]
def ==(other) #

Returns true if the raw object is equal to other.


[View source]
def [](index_or_key) : self #

Assumes the underlying value is an Array or Hash and returns the element at the given index_or_key.

Raises if the underlying value is not an Array nor a Hash.


[View source]
def []?(index_or_key) : self? #

Assumes the underlying value is an Array or Hash and returns the element at the given index_or_key, or nil if out of bounds or the key is missing.

Raises if the underlying value is not an Array nor a Hash.


[View source]
def as_a : Array(self) #

Checks that the underlying value is Array(self), and returns its value. Raises otherwise.


def as_a? : Array(self)? #

Checks that the underlying value is Array(self), and returns its value. Returns nil otherwise.


def as_bool : Bool #

Checks that the underlying value is Bool, and returns its value. Raises otherwise.


def as_bool? : Bool? #

Checks that the underlying value is Bool, and returns its value. Returns nil otherwise.


def as_f : Float32 #

Checks that the underlying value is Float32, and returns its value. Raises otherwise.


def as_f64 : Float64 #

Checks that the underlying value is Float64, and returns its value. Raises otherwise.


def as_f64? : Float64? #

Checks that the underlying value is Float64, and returns its value. Returns nil otherwise.


def as_f? : Float32? #

Checks that the underlying value is Float32, and returns its value. Returns nil otherwise.


def as_h : Hash(String, self) #

Checks that the underlying value is Hash(String, self), and returns its value. Raises otherwise.


def as_h? : Hash(String, self)? #

Checks that the underlying value is Hash(String, self), and returns its value. Returns nil otherwise.


def as_i : Int32 #

Checks that the underlying value is Int32, and returns its value. Raises otherwise.


def as_i64 : Int64 #

Checks that the underlying value is Int64, and returns its value. Raises otherwise.


def as_i64? : Int64? #

Checks that the underlying value is Int64, and returns its value. Returns nil otherwise.


def as_i? : Int32? #

Checks that the underlying value is Int32, and returns its value. Returns nil otherwise.


def as_nil : Nil #

Checks that the underlying value is Nil, and returns its value. Raises otherwise.


def as_s : String #

Checks that the underlying value is String, and returns its value. Raises otherwise.


def as_s? : String? #

Checks that the underlying value is String, and returns its value. Returns nil otherwise.


def as_time : Time #

Checks that the underlying value is Time, and returns its value. Raises otherwise.


def as_time? : Time? #

Checks that the underlying value is Time, and returns its value. Returns nil otherwise.


def clone #

Returns a new Log::Metadata::Value instance with the #raw value #cloneed.


[View source]
def dig(index_or_key, *subkeys) : self #

Traverses the depth of a structure and returns the value, otherwise raises.


[View source]
def dig?(index_or_key, *subkeys) : self? #

Traverses the depth of a structure and returns the value. Returns nil if not found.


[View source]
def dup #

Returns a new Log::Metadata::Value instance with the #raw value #duped.


[View source]
def hash(hasher) #

See Object#hash(hasher)


def inspect(io : IO) : Nil #
Description copied from struct Struct

Appends this struct's name and instance variables names and values to the given IO.

struct Point
  def initialize(@x : Int32, @y : Int32)
  end
end

p1 = Point.new 1, 2
p1.to_s    # "Point(@x=1, @y=2)"
p1.inspect # "Point(@x=1, @y=2)"

[View source]
def raw : Type #

Returns the raw underlying value, a Type.


def size : Int #

Assumes the underlying value is an Array or Hash and returns its size.

Raises if the underlying value is not an Array or Hash.


[View source]
def to_s(io : IO) : Nil #
Description copied from struct Struct

Same as #inspect(io).
