Struct PosSpan 

pub struct PosSpan {
    pub first: Pos,
    pub last: Pos,
}

PosSpan defines a text selection where first and last are the position of the first and last character. When first > last, no text is selected.

Fields

first: Pos

last: Pos

Trait Implementations

impl AddAssign<&PosSpan> for PosSpan

fn add_assign(&mut self, rhs: &PosSpan)

Performs the += operation.

impl Clone for PosSpan

fn clone(&self) -> PosSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PosSpan

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

Formats the value using the given formatter.

impl Default for PosSpan

fn default() -> PosSpan

Returns the “default value” for a type.

impl Display for PosSpan

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

Formats the value using the given formatter.

impl PartialEq for PosSpan

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