Function resolve_committish 

Source 
pub fn resolve_committish(committish: &str) -> Result<String>
Expand description

Resolves a committish reference to a full SHA-1 hash and verifies the commit exists.

This function takes any valid Git committish (commit hash, branch name, tag, or relative reference like HEAD~3) and resolves it to the full 40-character SHA-1 hash of the underlying commit object. It also validates that the commit object actually exists in the repository.

§Arguments

  • committish - A Git committish reference (e.g., “HEAD”, “main”, “a1b2c3d”, “HEAD~3”)

§Returns

  • Ok(String) - The full SHA-1 hash of the resolved commit
  • Err - If the committish cannot be resolved or the commit does not exist

§Examples

let sha = resolve_committish("HEAD").unwrap();
assert_eq!(sha.len(), 40); // Full SHA-1 hash
