Enum Format 

#[non_exhaustive]
pub enum Format {
    Djot,
    Markdown,
    Xml,
    Html,
    Asciidoc,
}

Every format Twig can parse — the input axis, as opposed to Target, which is where output bytes can go.

#[non_exhaustive] for the same reason Target is: Twig’s parser list grows (reStructuredText is written and awaiting a registry entry), and a caller matching on this enum should not have to be recompiled to keep compiling. Match with a _ arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Html

Asciidoc

Parsed and rendered, but not serialized: Target::Asciidoc reports Error::UnsupportedFormat, and no Editor gesture applies to an AsciiDoc document.

The parser also covers a slice of AsciiDoc rather than all of it — the header, paragraphs, sections, lists, delimited blocks and the inline spans. What it does not implement survives as literal source text rather than failing the parse, so a successful parse is not by itself a claim that the whole document was understood.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Format

impl Debug for Format

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

Formats the value using the given formatter.

impl Eq for Format

impl From<Format> for TwigFormat

fn from(value: Format) -> Self

Converts to this type from the input type.

impl From<Format> for Target

Total: every input format is also an output target, even the ones with no serializer yet (converting into XML reports Error::UnsupportedFormat rather than being unnameable).

fn from(value: Format) -> Self

Converts to this type from the input type.

impl PartialEq for Format

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

Equality operator ==.

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

Inequality operator !=.
