Struct ObjectId 

pub struct ObjectId { /* private fields */ }

What: A complete Git object name: 40 or 64 lowercase hexadecimal digits. The field is private, so the only way to obtain a value is parse_object_id. String owns the text (sibling &str would borrow Git’s output buffer). Hash lets the value be a HashMap key. Why: A value of this type is safe to send as one request line: it cannot contain a line feed, a space or a revision expression. The name outlives the Git output it was parsed from, so it owns its text.

In TS you’d write (pseudocode):

type ObjectId = string & { readonly brand: 'ObjectId' };

Implementations

impl ObjectId

What: impl ObjectId { ... } attaches a read-only accessor, like a class getter. Why: Callers print or send the name without being able to change it.

In TS you’d write (pseudocode):

// a branded string is used directly

pub fn as_str(&self) -> &str

What: Lend the name as text. &self borrows the value read-only; &str is a borrowed view into the owned String. Why: Request lines and Git arguments are built from this view without copying.

In TS you’d write (pseudocode):

toString(): string
