Enum BuildError 

pub enum BuildError {
    KindMissing,
    PayloadTooLarge {
        encoded_len: usize,
        max: u32,
    },
    FlagsNotAllowedForKind {
        kind: MessageKind,
        flags: u8,
    },
}

Errors surfaced at build() time so they fail at construction rather than at encode time, where the call site has already lost the context to recover.

Distinct from crate::redwire::codec::FrameError, which covers decode-side framing errors. The split keeps producer-side invariants (this) separate from consumer-side parsing (that).

Variants

KindMissing

kind() was never called — a frame has no default kind so the builder refuses to guess.

PayloadTooLarge

The encoded frame would exceed MAX_FRAME_SIZE.

Fields

encoded_len: usize

max: u32

FlagsNotAllowedForKind

Catalog cross-check failed: the requested flag set isn’t in MessageKind::allowed_flags() for the chosen kind.

Fields

kind: MessageKind

flags: u8

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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 PartialEq for BuildError

fn eq(&self, other: &BuildError) -> 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.
