Struct HeadingLevel 

pub struct HeadingLevel(/* private fields */);

Markdown heading level (1-6)

Markdown supports exactly 6 levels of headings, from # (level 1) through ###### (level 6). This type enforces that constraint at both compile time (after construction) and runtime (during config deserialization).

Implementations

impl HeadingLevel

pub fn new(level: u8) -> Result<Self, HeadingLevelError>

Create a new heading level, validating it’s in the range 1-6.

Errors

Returns HeadingLevelError if the level is not between 1 and 6 inclusive.

pub fn get(self) -> u8

Get the underlying heading level value (1-6).

pub fn as_usize(self) -> usize

Convert to usize for compatibility with existing code.

Trait Implementations

impl Clone for HeadingLevel

fn clone(&self) -> HeadingLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeadingLevel

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

Formats the value using the given formatter.

impl Default for HeadingLevel

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HeadingLevel

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for HeadingLevel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for HeadingLevel

fn cmp(&self, other: &HeadingLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for HeadingLevel

fn eq(&self, other: &HeadingLevel) -> 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.

impl PartialOrd for HeadingLevel

fn partial_cmp(&self, other: &HeadingLevel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for HeadingLevel

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
