Function tokio::fs::read_to_string

pub async fn read_to_string(path: impl AsRef<Path>) -> Result<String>

Creates a future which will open a file for reading and read the entire contents into a string and return said string.

This is the async equivalent of std::fs::read_to_string.

This operation is implemented by running the equivalent blocking operation on a separate thread pool using spawn_blocking.

Examples

use tokio::fs;

let contents = fs::read_to_string("foo.txt").await?;
println!("foo.txt contains {} bytes", contents.len());
