Enum GrpcWebCtx 

pub enum GrpcWebCtx {
    Disabled,
    Init,
    Upgrade,
    Trailers,
    Done,
}

Used for bridging gRPC to gRPC-web and vice-versa. See gRPC-web spec and gRPC h2 spec for more details.

Implementations

impl GrpcWebCtx

pub fn init(&mut self)

pub fn request_header_filter(&mut self, req: &mut RequestHeader)

gRPC-web request is fed into this filter, if the module is initialized we attempt to convert it to a gRPC request

pub fn response_header_filter(&mut self, resp: &mut ResponseHeader)

gRPC response is fed into this filter, if the module is in the bridge state attempt to convert the response it to a gRPC-web response

pub fn response_trailer_filter( &mut self, resp_trailers: &mut HeaderMap, ) -> Result<Option<Bytes>, Box<Error>>

Used to convert gRPC trailers into gRPC-web trailers, note gRPC-web trailers are encoded into the response body so we return the encoded bytes here.

Trait Implementations

impl Debug for GrpcWebCtx

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for GrpcWebCtx

fn default() -> GrpcWebCtx

Returns the “default value” for a type.

impl PartialEq for GrpcWebCtx

fn eq(&self, other: &GrpcWebCtx) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
