Implementations§

source§

impl Options

source

pub const ENABLE_TABLES: Self = _

source

pub const ENABLE_FOOTNOTES: Self = _

GitHub-compatible footnote syntax.

Footnotes are referenced with the syntax [^IDENT], and defined with an identifier followed by a colon at top level.


Footnote referenced [^1].

[^1]: footnote defined

Footnote referenced 1.


  1. footnote defined 

source

pub const ENABLE_STRIKETHROUGH: Self = _

source

pub const ENABLE_TASKLISTS: Self = _

source

pub const ENABLE_SMART_PUNCTUATION: Self = _

source

pub const ENABLE_HEADING_ATTRIBUTES: Self = _

Extension to allow headings to have ID and classes.

# text { #id .class1 .class2 myattr other_attr=myvalue } is interpreted as a level 1 heading with the content text, ID id, classes class1 and class2 and custom attributes myattr (without value) and other_attr with value myvalue. Note that ID, classes, and custom attributes should be space-separated.

source

pub const ENABLE_YAML_STYLE_METADATA_BLOCKS: Self = _

Metadata blocks in YAML style, i.e.:

  • starting with a --- line
  • ending with a --- or ... line
source

pub const ENABLE_PLUSES_DELIMITED_METADATA_BLOCKS: Self = _

Metadata blocks delimited by:

  • +++ line at start
  • +++ line at end
source

pub const ENABLE_OLD_FOOTNOTES: Self = _

Older footnote syntax. This flag implies ENABLE_FOOTNOTES, changing it to use an older syntax instead of the new, default, GitHub-compatible syntax.

New syntax is different from the old syntax regarding indentation, nesting, and footnote references with no definition:

[^1]: In new syntax, this is two footnote definitions.
[^2]: In old syntax, this is a single footnote definition with two lines.

[^3]:

    In new syntax, this is a footnote with two paragraphs.

    In old syntax, this is a footnote followed by a code block.

In new syntax, this undefined footnote definition renders as
literal text [^4]. In old syntax, it creates a dangling link.

Get a flags value with all bits unset.

source

pub const fn all() -> Self

Get a flags value with all known bits set.

source

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

source

Convert from a bits value.

This method will return None if any unknown bits are set.

source

Convert from a bits value, unsetting any unknown bits.

source

pub const fn from_bits_retain(bits: u32) -> Self

Convert from a bits value exactly.

source

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

source

The bitwise or (|) of the bits in two flags values.

source

pub fn remove(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

source

pub fn toggle(&mut self, other: Self)

The bitwise exclusive-or (^) of the bits in two flags values.

source

pub fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

source

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

The bitwise exclusive-or (^) of the bits in two flags values.

source

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

source§

impl Options

source

pub const fn iter(&self) -> Iter<Options>

source

pub const fn iter_names(&self) -> IterNames<Options>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
