Enum GrpcError 

#[non_exhaustive]
pub enum GrpcError {
    H2(H2Error),
    InvalidMessage(String),
    MaxSizeExceeded(String),
    NotReady,
}

Errors produced by the gRPC framing layer.

Marked #[non_exhaustive] because the crate is still evolving.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

H2(H2Error)

Underlying HTTP/2 error.

InvalidMessage(String)

Invalid gRPC message framing (truncated prefix, etc.).

MaxSizeExceeded(String)

A configured resource cap was exceeded — e.g. a single gRPC message claiming a length over max_message_size, decompressed output over max_decompressed_size, or a per-stream reassembly buffer over the max-message threshold.

NotReady

Connection is not ready (settings exchange incomplete).

Trait Implementations

impl Debug for GrpcError

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

Formats the value using the given formatter.

impl Display for GrpcError

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

Formats the value using the given formatter.

impl Error for GrpcError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<H2Error> for GrpcError

fn from(e: H2Error) -> Self

Converts to this type from the input type.
