Struct IsolatedMergeInput 

pub struct IsolatedMergeInput<'a> {
    pub real_git: &'a Path,
    pub overlay: &'a [(OsString, OsString)],
    pub identity: &'a WorktreeIdentity,
    pub command: &'a ResolvedCommand,
    pub environment: &'a [(OsString, OsString)],
}

Everything one isolated merge reads from its invocation.

In TS you’d write (pseudocode):

type IsolatedMergeInput = { realGit; overlay; identity; command; environment };

Fields

real_git: &'a Path

Real Git executable.

overlay: &'a [(OsString, OsString)]

Variables added to every Git child, the landing lease included.

identity: &'a WorktreeIdentity

The repository shape of the invocation.

command: &'a ResolvedCommand

The merge command after alias resolution.

environment: &'a [(OsString, OsString)]

The environment the invocation inherited.
