    // Required methods
    fn metadata(&self) -> Result<Metadata>;

Required Methods

fn metadata(&self) -> Result<Metadata>

fn set_len(&self, new_size: u64) -> Result<()>

Truncates or extends the size of the file. If the file is extended, the file will be null-padded at the end. The file cursor never changes when truncating or extending, even if the cursor would be put outside the file bounds by this operation.

Provided Methods

fn as_file(&mut self) -> &mut Self

where Self: Sized,

Casts a mutable reference to this file into &mut luminol_filesystem::File.

Trait Implementations

impl File for Box<dyn File>

fn metadata(&self) -> Result<Metadata>

fn set_len(&self, new_size: u64) -> Result<()>

Truncates or extends the size of the file. If the file is extended, the file will be null-padded at the end. The file cursor never changes when truncating or extending, even if the cursor would be put outside the file bounds by this operation.

fn as_file(&mut self) -> &mut Self

where Self: Sized,

Casts a mutable reference to this file into &mut luminol_filesystem::File.
