Struct bo::RowIndex

pub struct RowIndex {
    pub value: usize,
}

This module defines types which role is to abstract the different coordinate and indexing systems the editor has to support. Humans deal with line numbers, starting at 1, which maps to document rows, starting at 0. We define simple types in order to delegate the +1/-1 conversions to them, as it has proven easy to forget these only when dealing with usize values.

Fields

value: usize

Implementations

impl RowIndex

pub fn new(value: usize) -> Self

pub fn next(&self) -> Self

Trait Implementations

impl Clone for RowIndex

fn clone(&self) -> RowIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowIndex

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

Formats the value using the given formatter.

impl From<LineNumber> for RowIndex

fn from(ln: LineNumber) -> Self

Converts to this type from the input type.

impl From<RowIndex> for LineNumber

fn from(ri: RowIndex) -> Self

Converts to this type from the input type.

impl PartialEq<RowIndex> for RowIndex

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

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

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

This method tests for !=.
