Struct nvimpam_lib::lines::Lines

pub struct Lines<'a>(_);

The struct to hold the lines.

Methods

impl<'a> Lines<'a>

pub fn len(&self) -> usize

Returns the number of lines

pub fn is_empty(&self) -> bool

Check if there are any lines

pub fn from_vec(v: Vec<String>) -> Lines<'a>

Create a new Lines struct from a Vec<String>

pub fn from_strs(v: &'a [&'a str]) -> Lines<'a>

Creates a new Lines struct from a slice of &'strs

pub fn from_slice(v: &'a [u8]) -> Lines<'a>

Create a new Lines struct from a byte slice by splitting on newlines.

pub fn read_file<P: AsRef<Path>>(path: P) -> Result<Vec<u8>, Error>

Read a file into a Vec<u8>. For usage with from_slice.

pub fn update(&mut self, first: usize, last: usize, linedata: Vec<String>)

Update Lines:

• first and last are zero-indexed (just as Lines itself)
• last is the first line that has not been updated This are the exact conditions to use the range first..last together with splice on a Vec.

Important traits for LinesIter<'a, I>

impl<'a, I> Iterator for LinesIter<'a, I> where
    I: Iterator<Item = &'a Line<'a>>,  type Item = &'a [u8];

pub fn iter(     &'a self ) -> LinesIter<'a, impl Iterator<Item = &'a Line<'a>>>

Return an Iterator over the lines of a file.

Trait Implementations

impl<'a> Default for Lines<'a>

fn default() -> Lines<'a>

impl<'a> Deref for Lines<'a>

type Target = [Line<'a>]
