package metadata

import "google.golang.org/grpc/internal/metadata"

Package metadata contains functions to set and get metadata from addresses.

This package is experimental.

Index ¶

• func Get(addr resolver.Address) metadata.MD
• func Set(addr resolver.Address, md metadata.MD) resolver.Address
• func Validate(md metadata.MD) error

Functions ¶

func Get ¶

func Get(addr resolver.Address) metadata.MD

Get returns the metadata of addr.

func Set ¶

func Set(addr resolver.Address, md metadata.MD) resolver.Address

Set sets (overrides) the metadata in addr.

When a SubConn is created with this address, the RPCs sent on it will all have this metadata.

func Validate ¶

func Validate(md metadata.MD) error

Validate returns an error if the input md contains invalid keys or values.

If the header is not a pseudo-header, the following items are checked: - header names must contain one or more characters from this set [0-9 a-z _ - .]. - if the header-name ends with a "-bin" suffix, no validation of the header value is performed. - otherwise, the header value must contain one or more characters from the set [%x20-%x7E].
