Struct FileView 

pub struct FileView { /* private fields */ }

A text file, from cx.file_view(path). Its text is read at once and again when it changes on disk. A clone is cheap and shares it.

Implementations

impl FileView

pub fn text(&self) -> ReadSignal<Option<String>>

The file’s text, or None while it is missing, can’t be read, isn’t UTF-8, or is over 16 MiB, each logged once until it reads again.

pub fn write(&self, text: impl AsRef<str>)

Replaces the file’s text, through a new file beside it renamed over it, so a reader never sees half of it, making its directory if it is missing. A link is followed and the file it names is replaced, keeping its permissions. A failure is logged and the text stays as it was.

Trait Implementations

impl Clone for FileView

fn clone(&self) -> Self

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