Struct IndentLevel 

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

Available on crate feature blob only.

Represents the indentation level of a line.

Indentation is measured in spaces, with tabs expanded according to a configurable tab width. Special values are used to represent blank lines and maximum indentation.

Implementations

impl IndentLevel

pub fn for_ascii_line( src: impl IntoIterator<Item = u8>, tab_width: u8, ) -> IndentLevel

Computes the indentation level for an ASCII line.

Parameters

• src - An iterator over the bytes of the line
• tab_width - The number of spaces that a tab character represents (min is 1)

Returns

The computed indentation level, or BLANK if the line contains only whitespace

pub fn for_line( src: impl IntoIterator<Item = char>, tab_width: u8, ) -> IndentLevel

Computes the indentation level for a Unicode line.

Parameters

• src - An iterator over the characters of the line
• tab_width - The number of spaces that a tab character represents

Returns

The computed indentation level, or BLANK if the line contains only whitespace

Trait Implementations

impl Clone for IndentLevel

fn clone(&self) -> IndentLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndentLevel

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

Formats the value using the given formatter.

impl Hash for IndentLevel

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

where __H: Hasher,

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 PartialEq for IndentLevel

fn eq(&self, other: &IndentLevel) -> 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 IndentLevel

fn partial_cmp(&self, other: &IndentLevel) -> 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.
