Function strftime

pub fn strftime(
    time: &impl Time,
    format: &[u8],
    buf: &mut dyn Write,
) -> Result<(), Error>

Available on crate feature std only.

Format a time implementation with the specified format byte string, writing to the provided std::io::Write object.

See the crate-level documentation for a complete description of possible format specifiers.

Allocations

This strftime implementation makes no heap allocations on its own, but the provided writer may allocate.

Examples

use strftime::io::strftime;
use strftime::Time;

// Not shown: create a time implementation with the year 1970
// let time = ...;
assert_eq!(time.year(), 1970);

let mut buf = Vec::new();
strftime(&time, b"%Y", &mut buf)?;
assert_eq!(buf, *b"1970");

Errors

Can produce an Error when the formatting fails.
