Function Documentation

int grpc_channel_args_compression_algorithm_get_states

(

const grpc_channel_args *

a

)

Returns the bitset representing the support state (true for enabled, false for disabled) for compression algorithms.

The i-th bit of the returned bitset corresponds to the i-th entry in the grpc_compression_algorithm enum.

grpc_channel_args* grpc_channel_args_compression_algorithm_set_state	(	grpc_channel_args **	a,
		grpc_compression_algorithm	algorithm,
		int	enabled
	)

Sets the support for the given compression algorithm.

By default, all compression algorithms are enabled. It's an error to disable an algorithm set by grpc_channel_args_set_compression_algorithm.

Returns an instance will the updated algorithm states. The a pointer is modified to point to the returned instance (which may be different from the input value of a).

grpc_channel_args* grpc_channel_args_copy

(

const grpc_channel_args *

src

)

grpc_channel_args* grpc_channel_args_copy_and_add	(	const grpc_channel_args *	src,
		const grpc_arg *	to_add,
		size_t	num_to_add
	)

Copy some arguments and add the to_add parameter in the end.

If to_add is NULL, it is equivalent to call grpc_channel_args_copy.

void grpc_channel_args_destroy

(

grpc_channel_args *

a

)

Destroy arguments created by grpc_channel_args_copy.

grpc_compression_algorithm grpc_channel_args_get_compression_algorithm

(

const grpc_channel_args *

a

)

Returns the compression algorithm set in a.

int grpc_channel_args_is_census_enabled

(

const grpc_channel_args *

a

)

Reads census_enabled settings from channel args.

Returns 1 if census_enabled is specified in channel args, otherwise returns 0.

grpc_channel_args* grpc_channel_args_merge	(	const grpc_channel_args *	a,
		const grpc_channel_args *	b
	)

Copy args from a then args from b into a new channel args.

grpc_channel_args* grpc_channel_args_set_compression_algorithm	(	grpc_channel_args *	a,
		grpc_compression_algorithm	algorithm
	)

Returns a channel arg instance with compression enabled.

If a is non-NULL, its args are copied. N.B. GRPC_COMPRESS_NONE disables compression for the channel.
