Function smol::fs::read

pub async fn read<P>(path: P) -> Result<Vec<u8, Global>, Error> where
    P: AsRef<Path>, 

Reads the entire contents of a file as raw bytes.

This is a convenience function for reading entire files. It pre-allocates a buffer based on the file size when available, so it is typically faster than manually opening a file and reading from it.

If you want to read the contents as a string, use read_to_string() instead.

Errors

An error will be returned in the following situations:

• path does not point to an existing file.
• The current process lacks permissions to read the file.
• Some other I/O error occurred.

Examples

let contents = async_fs::read("a.txt").await?;
