Struct BuildInfo 

pub struct BuildInfo {
    pub name: &'static str,
    pub version: &'static str,
    pub commit: Option<&'static str>,
    pub built_at: Option<&'static str>,
    pub profile: &'static str,
}

The identity of a running binary.

Build it with build_info!, which fills it in from the crate being compiled.

Every field is &'static str, because every value is known when the binary is — so this costs nothing to hold and nothing to clone. That is also why it is Serialize and not Deserialize: a service reads its own build info, and a client reading somebody else’s wants its own owned type.

Fields

name: &'static str

The package name.

version: &'static str

The package version.

commit: Option<&'static str>

The commit this was built from, if the build was told.

built_at: Option<&'static str>

When it was built, if the build was told.

profile: &'static str

debug or release.

Implementations

impl BuildInfo

pub fn short_commit(&self) -> Option<&str>

The commit, shortened to the first seven characters.

What everybody actually pastes into a chat message.

pub fn is_debug(&self) -> bool

Whether this is a debug build.

Worth asserting at boot in production: a debug binary is several times slower, and the difference is easy to deploy by accident.

pub fn summary(&self) -> String

One line, for a boot log.

identity 2.4.1 (9f3c2ab, release)
