Struct InsertPosition

pub struct InsertPosition { /* private fields */ }

Describes a position between two characters.

Implementations

impl InsertPosition

pub fn new(line: usize, col: usize) -> Self

Crate a new InsertPosition from raw parts

pub fn line(&self) -> usize

The line this position is on. 1 is the first line.

This is always equals to the number of inc_line() calls + 1 made on this position.

pub fn col(&self) -> usize

The column to the left of the position. 0 is the first insert position, when there is no column left of the position.

This is always equals to the number of inc_col() calls made on this position after the last inc_line() call.

pub fn inc_col(&mut self)

Move the position forward by one non-newline character.

pub fn inc_line(&mut self)

Move the position forward by one newline character.

pub fn inc(&mut self, c: char)

Move the position forward by one character. If the character c is a newline, it behaves like [inc_line()], otherwhise it behaves like [inc_col()].

Trait Implementations

impl Clone for InsertPosition

fn clone(&self) -> InsertPosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InsertPosition

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

Formats the value using the given formatter.

impl Default for InsertPosition

fn default() -> Self

Returns the “default value” for a type.

impl Display for InsertPosition

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

Formats the value using the given formatter.

impl FromStr for InsertPosition

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for InsertPosition

fn cmp(&self, other: &InsertPosition) -> 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 InsertPosition

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

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