Expand description

Extension trait for databases that use a WritableSystem.

Provides various helper function that ease testing.

Required Associated Types§

Source

type System: WritableSystem

Required Methods§

Source

fn writable_system(&self) -> &Self::System

Provided Methods§

Source

fn write_file( &mut self, path: impl AsRef<SystemPath>, content: impl AsRef<str>, ) -> Result<()>

Writes the content of the given file and notifies the Db about the change.

Source

fn write_dedented(&mut self, path: &str, content: &str) -> Result<()>

Writes auto-dedented text to a file.

Source

fn write_files<P, C, I>(&mut self, files: I) -> Result<()>
where I: IntoIterator<Item = (P, C)>, P: AsRef<SystemPath>, C: AsRef<str>,

Writes the content of the given files and notifies the Db about the change.

This trait is not dyn compatible.

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