Struct WalkFailure 

#[non_exhaustive]
pub struct WalkFailure {
    pub error: IrError,
    pub component_path: Vec<String>,
    pub counts: WalkCounts,
}

A walk that stopped: why, where, and how far it had got.

The partial HTML is dropped: nothing a failed walk wrote leaves it.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

error: IrError

Why it stopped.

component_path: Vec<String>

The component names of the islands open where it stopped, outermost first; empty when it stopped outside every island. FMIR v2 carries no source positions, so a component the compiler inlined into its parent has no name here; the source-position table of FMIR v3 adds it.

counts: WalkCounts

What it had written by then.

Trait Implementations

impl Clone for WalkFailure

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for WalkFailure

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

Formats the value using the given formatter.

impl Eq for WalkFailure

impl Error for WalkFailure

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 WalkFailure

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

Equality operator ==.

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

Inequality operator !=.
