Enum GitReference 

pub enum GitReference {
    Branch(String),
    Tag(String),
    Rev(String),
    DefaultBranch,
}

The git reference a dependency tracks, derived from its branch/tag/rev fields.

Variants

Branch(String)

Tip of a named branch. Mutable: re-resolved online each build.

Tag(String)

A tag. Immutable: reused from cache once fetched.

Rev(String)

A revision (commit-ish). Immutable: reused from cache once fetched.

DefaultBranch

The repository’s default branch. Mutable, like Branch.

Implementations

impl GitReference

pub fn is_mutable(&self) -> bool

Whether the reference tracks a moving target (a branch tip) and must be re-resolved online.

pub fn lock_string(&self) -> String

Stable string form stored in leo.lock; a change here forces re-resolution.

pub fn from_opts( branch: &Option<String>, tag: &Option<String>, rev: &Option<String>, ) -> Result<GitReference, &'static str>

Build a reference from branch/tag/rev, defaulting to DefaultBranch. Errors if more than one is set, or if rev isn’t a commit hash (a symbolic revspec like HEAD is not a stable pin).

Trait Implementations
