Trait Files

Reads a design’s files by their path from the top of the served folder.

Required Methods

fn bytes(&self, path: &str) -> Option<Vec<u8>>

A file’s bytes: a design’s text, an Image’s file or a font file.

fn list(&self, path: &str) -> Option<Vec<String>>

The names of the files directly in the folder at path, sorted; None when there is no such folder. A font folder is read this way.

Provided Methods

fn read(&self, path: &str) -> Option<String>

A design file’s text.

fn parse(&self, path: &str, source: &str) -> Result<Arc<File>, Problem>

The design file at path, whose text is source, parsed. A store that keeps files between resolves matches it against the file’s last parse (crate::ids::matched), so its elements keep their ids — and the nodes they make theirs — across saves.

fn image(&self, path: &str) -> Option<Result<Arc<ImageFile>, String>>

The image file at path, decoded, or why it doesn’t decode; None when there is no such file. A store that keeps files between resolves keeps their decoded images too, so a save doesn’t decode them again.

fn font(&self, path: &str) -> Option<Result<Arc<FontFile>, String>>

The font file at path, checked, or why it isn’t one; None when there is no such file. A store that keeps files between resolves keeps them checked too.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
