Enum IcRequestError 

pub enum IcRequestError {
    UnsupportedVersion(u16),
    InvalidTarget,
    SnapshotRequired,
    UnexpectedSnapshot,
    InvalidSnapshotId,
    Encoding(String),
    ArgumentsTooLarge,
    EffectMismatch {
        expected: IcRequestEffect,
    },
    TargetMismatch,
    DigestMismatch,
}

Typed closed IC request, exact byte binding or codec admission failure.

Variants

UnsupportedVersion(u16)

Other product generations are not maintained.

InvalidTarget

Target text is not a bounded canonicalizable principal.

SnapshotRequired

Load requires exact raw snapshot bytes.

UnexpectedSnapshot

A method that has no snapshot argument received one.

InvalidSnapshotId

Snapshot bytes are empty or exceed their finite bound.

Encoding(String)

The pinned upstream Candid encoder rejected the typed arguments.

ArgumentsTooLarge

Derived argument size exceeds the codec bound.

EffectMismatch

A mutation and observation request cannot substitute for each other.

Fields

expected: IcRequestEffect

Required semantic class, independent of replicated call mode.

TargetMismatch

The payload/routing target differs from the original operation target.

DigestMismatch

Exact method/argument digest differs from its original reservation.

Trait Implementations

impl Debug for IcRequestError

impl Eq for IcRequestError

impl Error for IcRequestError

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)
