Enum stam::Cursor

pub enum Cursor {
    BeginAligned(usize),
    EndAligned(isize),
}

A cursor points to a specific point in a text. I Used to select offsets. Units are unicode codepoints (not bytes!) and are 0-indexed.

The cursor can be either begin-aligned or end-aligned. Where BeginAlignedCursor(0) is the first unicode codepoint in a referenced text, and EndAlignedCursor(0) the last one.

Variants

BeginAligned(usize)

Cursor relative to the start of a text. Has a value of 0 or higher

EndAligned(isize)

Cursor relative to the end of a text. Has a value of 0 or lower. The last character of a text begins at EndAlignedCursor(-1) and ends at EndAlignedCursor(0)

Trait Implementations

impl Clone for Cursor

fn clone(&self) -> Cursor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cursor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cursor

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Cursor

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

Formats the value using the given formatter.

impl From<usize> for Cursor

fn from(cursor: usize) -> Self

Converts to this type from the input type.

impl PartialEq<Cursor> for Cursor

fn eq(&self, other: &Cursor) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Cursor

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for Cursor

type Error = StamError

The type returned in the event of a conversion error.

fn try_from(cursor: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<isize> for Cursor

type Error = StamError

The type returned in the event of a conversion error.

fn try_from(cursor: isize) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Cursor

impl StructuralPartialEq for Cursor
