Enum SnippetError 

pub enum SnippetError {
    DuplicateIndex(u16),
    Nesting,
    Malformed(&'static str),
}

Why a snippet body failed to parse. Real spec.rs snippets never trigger these (its own suite pins validity); the insertion path treats a failure as “insert the raw body verbatim” behind a debug_assert, so this stays a clean Result here.

Variants

DuplicateIndex(u16)

The same placeholder index appeared twice (mirrored placeholders are unsupported). 0 reports the final stop ($0).

Nesting

A placeholder appeared inside a default (defaults are literal text).

Malformed(&'static str)

A malformed placeholder token.

Trait Implementations

impl Eq for SnippetError

impl Error for SnippetError

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
