Awscr::Signer::Header

Inherits Comparable < Comparable < Reference < Object

Represents a Header as defined by the signing spec.

header = Header.new("k", "v")
header.to_s # => k:v

header.merge("value2")
header.to_s # => k:v,value2

Constructors

Instance methods

<=>(other : Header) : Int

Source

<=>(other : String) : Int

The comparison operator. Returns 0 if the two objects are equal, a negative number if this object is considered less than other, a positive number if this object is considered greater than other, or nil if the two objects are not comparable.

Subclasses define this method to provide class-specific ordering.

The comparison operator is usually used to sort values:

# Sort in a descending way:
[3, 1, 2].sort { |x, y| y <=> x } # => [3, 2, 1]

# Sort in an ascending way:
[3, 1, 2].sort { |x, y| x <=> y } # => [1, 2, 3]

Source

key

Returns the key as a string.

Source

merge(hdr : Header) : Bool

Merges a header into the current header values

Source

merge(value : String) : Bool

Merges a value into the header's values

Source

to_s(io : IO)

Return the canonical string representation
