Enum FrameError 

#[non_exhaustive]
pub enum FrameError {
    TooShort(usize),
    BadMagic {
        expected: [u8; 4],
        got: [u8; 4],
    },
    PayloadTruncated {
        compressed_size: u64,
        remaining: usize,
    },
    UnknownCodec(u32),
    PayloadTooLarge(u64),
}

v1.0 stability: #[non_exhaustive] — new framing-level validation errors may be added in minor releases. Downstream callers must include a _ => arm when matching on this enum.

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.

TooShort(usize)

BadMagic

Fields

expected: [u8; 4]

got: [u8; 4]

PayloadTruncated

Fields

compressed_size: u64

remaining: usize

UnknownCodec(u32)

PayloadTooLarge(u64)

v0.8.15 H-b: a frame’s declared compressed_size (or padding frame length) exceeds the target architecture’s usize::MAX. On 64-bit hosts this is unreachable; on the 32-bit wasm32-unknown-unknown target the as usize cast used to truncate, letting a forged 4 GiB+ frame parse as a 64-byte payload (silent data loss in the browser decoder). try_from-based validation forces the typed error instead.

Trait Implementations

impl Debug for FrameError

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

Formats the value using the given formatter.

impl Display for FrameError

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

Formats the value using the given formatter.

impl Error for FrameError

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.
