`class Encoding`

The grpc-encoding header represents the message compression encoding.

The grpc-encoding header specifies the compression algorithm used for the message payload. Common values include "identity" (no compression), "gzip", "deflate", etc. This header can appear in both request and response headers, but not in trailers.

Definitions

`def self.parse(value)`

Parse an encoding from a header value.

Signature

parameter　value　String: The header value to parse (e.g., "identity", "gzip").
returns　Encoding: A new Encoding instance.

Implementation

def self.parse(value)
	new(value)
end

`def self.coerce(value)`

Coerce a value to an Encoding instance. Used by Protocol::HTTP::Headers when setting header values.

Signature

parameter　value　Object: The value to coerce (will be converted to string).
returns　Encoding: A new Encoding instance.

Implementation

def self.coerce(value)
	new(value.to_s)
end

`def initialize(value)`

Initialize the encoding header with the given value.

Signature

parameter　value　String: The encoding value (e.g., "identity", "gzip").

Implementation

def initialize(value)
	super(value.to_s)
end

`def identity?`

Check if this encoding represents no compression (identity encoding).

Signature

returns　Boolean: true if the encoding is "identity" or empty.

Implementation

def identity?
	self == "identity" || self.empty?
end

`def <<(value)`

Merge another encoding value (takes the new value, as encoding should only appear once)

Signature

parameter　value　String: The new encoding value

Implementation

def <<(value)
	replace(value.to_s)
	
	return self
end

`def self.trailer?`

Whether this header is acceptable in HTTP trailers. The grpc-encoding header does not appear in trailers.

Signature

returns　Boolean: false, as grpc-encoding cannot appear in trailers.

Implementation

def self.trailer?
	false
end
