Struct SignedRole 

pub struct SignedRole<T> { /* private fields */ }

A signed role, including its serialized form (buffer) which is meant to be written to file. The sha256 and length are calculated from this buffer and included in metadata for other roles, which makes it imperative that this buffer is what is written to disk.

Convenience methods are provided on SignedRepository to ensure that each role’s buffer is written correctly.

Implementations

impl<T> SignedRole<T>

where T: Role + Serialize,

pub async fn new( role: T, key_holder: &KeyHolder, keys: &[Box<dyn KeySource>], rng: &(dyn SecureRandom + Sync), ) -> Result<Self>

Creates a new SignedRole

pub fn signed(&self) -> &Signed<T>

Provides access to the internal signed metadata object.

pub fn buffer(&self) -> &Vec<u8>

Provides access to the internal buffer containing the serialized form of the signed role. This buffer should be used anywhere this role is written to file.

pub fn sha256(&self) -> &[u8]

Provides the sha256 digest of the signed role.

pub fn length(&self) -> &u64

Provides the length in bytes of the serialized representation of the signed role.

pub async fn write<P>(&self, outdir: P, consistent_snapshot: bool) -> Result<()>

where P: AsRef<Path>,

Write the current role’s buffer to the given directory with the appropriate file name.

pub fn add_old_signatures(self, old_signatures: Vec<Signature>) -> Result<Self>

Append the old signatures for root role

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for SignedRole<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
