Module exec 

Structs

CommandOutput

Output from executing a command.

Enums

CommandError

Errors occurring during command execution.

Constants

REQUIRED_GIT

The minimum git version callisto supports, as a semver::VersionReq grammar string consumed directly by check_git_version — the single place this floor is defined, so the requirement used for the actual comparison and the one rendered in CommandError::IncompatibleVersion’s message can never drift apart.

Traits

CommandRunner

Trait for executing subprocess commands.

Functions

check_git_version

Validates git version against the REQUIRED_GIT floor.
