Enum Content 

#[non_exhaustive]
pub enum Content<'src> {
    Plain(&'src str),
    Segments(&'src [Segment<'src>]),
}

Body content for nodes whose textual payload may carry nested Aozora constructs.

Two-tier representation: Plain is the fast path for plain strings; Segments is the general case for content carrying nested aozora nodes.

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.

Plain(&'src str)

Plain text without embedded Aozora constructs. Borrows directly from source or from arena.

Segments(&'src [Segment<'src>])

Mixed text plus nested Aozora constructs. Slice owned by arena.

Implementations

impl<'src> Content<'src>

pub const EMPTY: Self

Empty content. By convention Segments(&[]) rather than Plain("") — same canonicalisation as the owned counterpart.

pub fn as_plain(self) -> Option<&'src str>

Fast-path accessor: returns the text if this is a Plain run, None if mixed. Renderers use this to skip the segment loop on the 99%+ majority case.

pub fn iter(self) -> ContentIter<'src>

Iterate segments left-to-right. Plain yields a single text segment; Segments yields each entry in order.

Trait Implementations

impl<'src> Clone for Content<'src>

fn clone(&self) -> Content<'src>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for Content<'src>

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

Formats the value using the given formatter.

impl Default for Content<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'src> IntoIterator for Content<'src>

type Item = Segment<'src>

The type of the elements being iterated over.

type IntoIter = ContentIter<'src>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'src> PartialEq for Content<'src>

fn eq(&self, other: &Content<'src>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
