Struct vergen::Rustc

pub struct Rustc { /* private fields */ }

Configuration for the VERGEN_RUSTC_* instructions

Instructions

The following instructions can be generated:

Instruction	Default
cargo:rustc-env=VERGEN_RUSTC_CHANNEL=nightly	*
cargo:rustc-env=VERGEN_RUSTC_COMMIT_DATE=2021-02-10	*
cargo:rustc-env=VERGEN_RUSTC_COMMIT_HASH=07194ffcd25b0871ce560b9f702e52db27ac9f77	*
cargo:rustc-env=VERGEN_RUSTC_HOST_TRIPLE=x86_64-apple-darwin	*
cargo:rustc-env=VERGEN_RUSTC_LLVM_VERSION=11.0	*
cargo:rustc-env=VERGEN_RUSTC_SEMVER=1.52.0-nightly	*

• If the channel field is false, the VERGEN_RUSTC_CHANNEL instruction will not be generated.
• If the commit_date field is false, the VERGEN_RUSTC_COMMIT_DATE instruction will not be generated.
• If the host_triple field is false, the VERGEN_RUSTC_HOST_TRIPLE instruction will not be generated.
• If the llvm_version field is false, the VERGEN_RUSTC_LLVM_VERSION instruction will not be generated.
• If the semver field is false, the VERGEN_RUSTC_SEMVER instruction will not be generated.
• If the sha field is false, the VERGEN_RUSTC_COMMIT_HASH instruction will not be generated.
• NOTE - The commit_date filed is only a date, as we are restricted to the output from rustc_version
• NOTE - The VERGEN_RUSTC_LLVM_VERSION instruction will only be generated on the nightly channel, regardless of the llvm_version field.
• NOTE - To keep processing other sections if an Error occurs in this one, set Rustc::skip_if_error to true.

Example

use vergen::{vergen, Config};

let mut config = Config::default();
// Turn off the LLVM instruction
*config.rustc_mut().llvm_version_mut() = false;

// Generate the instructions
vergen(config)?;
