Enum ValidationError 

pub enum ValidationError {
    ApiVersion {
        received: u32,
        supported: u32,
    },
    OutOfBounds {
        source_len: usize,
    },
    Overlap,
    EmptySpan,
    SpanLimit {
        limit: usize,
    },
}

Why a plugin’s answer cannot be trusted.

Each variant is a way a guest could otherwise make the host remove bytes it should not, or spend unbounded work trying.

Variants

ApiVersion

The guest was built against a different revision of this contract.

Fields

received: u32

The version the guest reported.

supported: u32

The only version this host accepts, API_VERSION.

OutOfBounds

A span is inverted or reaches past the end of the source.

Fields

source_len: usize

The length of the source the spans had to fit in.

Overlap

A span starts before its predecessor ends, which no single-pass edit could apply.

EmptySpan

A span covers no bytes, so it names no comment.

SpanLimit

More spans than the source could hold comments, which is a guest spending the host’s memory rather than reporting anything.

Fields

limit: usize

The most spans this source could have justified.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Eq for ValidationError

impl Error for ValidationError

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 ValidationError

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

Equality operator ==.

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

Inequality operator !=.
