Function Documentation

grpc_attach_md_to_error()

grpc_error* grpc_attach_md_to_error	(	grpc_error *	src,
		grpc_mdelem	md
	)

grpc_metadata_batch_add_head()

grpc_error* grpc_metadata_batch_add_head	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage,
		grpc_mdelem	elem_to_add
	)

Add elem_to_add as the first element in batch, using storage as backing storage for the linked list element.

storage is owned by the caller and must survive for the lifetime of batch. This usually means it should be around for the lifetime of the call. Takes ownership of elem_to_add

grpc_metadata_batch_add_tail()

grpc_error* grpc_metadata_batch_add_tail	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage,
		grpc_mdelem	elem_to_add
	)

Add elem_to_add as the last element in batch, using storage as backing storage for the linked list element.

storage is owned by the caller and must survive for the lifetime of batch. This usually means it should be around for the lifetime of the call. Takes ownership of elem_to_add

grpc_metadata_batch_assert_ok()

void grpc_metadata_batch_assert_ok

(

grpc_metadata_batch *

batch

)

grpc_metadata_batch_clear()

void grpc_metadata_batch_clear

grpc_metadata_batch_copy()

void grpc_metadata_batch_copy	(	grpc_metadata_batch *	src,
		grpc_metadata_batch *	dst,
		grpc_linked_mdelem *	storage
	)

Copies src to dst.

storage must point to an array of grpc_linked_mdelem structs of at least the same size as src.

grpc_metadata_batch_destroy()

grpc_metadata_batch_link_head() [1/2]

grpc_error* grpc_metadata_batch_link_head	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage
	)

Add storage to the beginning of batch.

storage->md is assumed to be valid. storage is owned by the caller and must survive for the lifetime of batch. This usually means it should be around for the lifetime of the call.

grpc_metadata_batch_link_head() [2/2]

grpc_error* grpc_metadata_batch_link_head	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage,
		grpc_metadata_batch_callouts_index	idx
	)

grpc_metadata_batch_link_tail() [1/2]

grpc_error* grpc_metadata_batch_link_tail	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage
	)

Add storage to the end of batch.

storage->md is assumed to be valid. storage is owned by the caller and must survive for the lifetime of batch. This usually means it should be around for the lifetime of the call.

grpc_metadata_batch_link_tail() [2/2]

grpc_error* grpc_metadata_batch_link_tail	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage,
		grpc_metadata_batch_callouts_index	idx
	)

grpc_metadata_batch_move()

void grpc_metadata_batch_move	(	grpc_metadata_batch *	src,
		grpc_metadata_batch *	dst
	)

grpc_metadata_batch_remove() [1/2]

void grpc_metadata_batch_remove	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage
	)

Remove storage from the batch, unreffing the mdelem contained.

grpc_metadata_batch_remove() [2/2]

void grpc_metadata_batch_remove	(	grpc_metadata_batch *	batch,
		grpc_metadata_batch_callouts_index	idx
	)

grpc_metadata_batch_set_value()

void grpc_metadata_batch_set_value	(	grpc_linked_mdelem *	storage,
		const grpc_slice &	value
	)

grpc_metadata_batch_substitute()

grpc_error* grpc_metadata_batch_substitute	(	grpc_metadata_batch *	batch,
		grpc_linked_mdelem *	storage,
		grpc_mdelem	new_mdelem
	)

Substitute a new mdelem for an old value.
