Crate esp_idf_hal::sys::build_time
Expand description
§build-time
Simple proc-macros to generate build timestamp string literals.
Based on Jasen Borisov’s build_timestamp crate.
Two function like procedures are provided: build_time_utc
and build_time_local
.
They take an optional strftime
date and time format string as input, and return a string literal.
If the input is empty, they will return a string literal in
RFC 3339 date and time format,
e.g., "2021-05-29T06:55:50.418437046+00:00"
.
Requires Rust 1.45+ because these macros are used in expression positions.
§Usage
use build_time::{build_time_utc, build_time_local};
// Returns the UTC build timestamp in RFC3339 date and time format.
let utc_build_time = build_time_utc!();
// Returns the local build timestamp in the specified format.
let local_build_time = build_time_local!("%Y-%m-%dT%H:%M:%S%.f%:z");
Macros§
- Build time in the local timescale.
- Build time in UTC.
