// Required methods
fn read_to_string(&self, path: &Path) -> Result<String>;
fn write_bytes(&self, path: &Path, contents: &[u8]) -> Result<()>;
}Expand description
File system operations that TeX may need to perform.
These operations are extracted to a trait so that they be mocked out in unit testing and in execution contexts like WASM.
Required Methods§
sourcefn read_to_string(&self, path: &Path) -> Result<String>
fn read_to_string(&self, path: &Path) -> Result<String>
Read the entire contents of a file into a string.
This is implemented by std::fs::read_to_string.
sourcefn write_bytes(&self, path: &Path, contents: &[u8]) -> Result<()>
fn write_bytes(&self, path: &Path, contents: &[u8]) -> Result<()>
Write a slice of bytes to a file.
This is implemented by std::fs::write.
