pub enum Location {
    Abs(usize),
    Rel(isize),
}

Variants

Abs(usize)

Absolute location

Rel(isize)

Relative location from cursor

Implementations

impl Location

pub fn Cursor() -> Location

Location at the cursor, alias of Location::Rel(0)

pub fn Before() -> Location

Location just before cursor, alias of Location::Rel(-1)

pub fn After() -> Location

Location just after cursor, alias of Location::Rel(1)

pub fn Front() -> Location

Location at beginning of buffer, alias of Location::Abs(0)

pub fn Back(cb: &CursorBuffer) -> Location

Location at end of buffer

pub fn FindChar(cb: &CursorBuffer, start: Location, c: char) -> Option<Location>

Location of the next occurrence of character

pub fn Find<P>( cb: &CursorBuffer, start: Location, predicate: P, ) -> Option<Location>

where Self: Sized, P: FnMut(char) -> bool,

Location of the next occurrence of predicate

pub fn FindCharBack( cb: &CursorBuffer, start: Location, c: char, ) -> Option<Location>

Location of the previous occurrence of character

pub fn FindBack<P>( cb: &CursorBuffer, start: Location, predicate: P, ) -> Option<Location>

where Self: Sized, P: FnMut(char) -> bool,

Location of the previous occurrence of predicate

Trait Implementations

impl Add for Location

type Output = Location

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for Location

fn clone(&self) -> Location

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Location

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

Formats the value using the given formatter.

impl Default for Location

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Location

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