## Utf8Pattern

# Enum Utf8Pattern

Source

    pub enum Utf8Pattern<'a> {
        StringPattern(&'a str),
        CharPattern(char),
    }

🔬This is a nightly-only experimental API. (`pattern` #27721)
Expand description

Result of calling `Pattern::as_utf8_pattern()`. Can be used for inspecting the contents of a `Pattern` in cases where the underlying representation can be represented as UTF-8.

## Variants§

§

### StringPattern(&'a str)

🔬This is a nightly-only experimental API. (`pattern` #27721)

Type returned by String and str types. This stores `str` rather than bytes so callers cannot describe non-UTF-8 string patterns through this API.

§

### CharPattern(char)

🔬This is a nightly-only experimental API. (`pattern` #27721)

Type returned by char types.
