Struct btlib::Writecap

pub struct Writecap { /* private fields */ }

Verifies that a principal is authorized to write blocks in a tree.

Implementations

impl Writecap

pub fn to_cert_chain( &self, subject_key: &AsymKeyPub<Sign> ) -> Result<Vec<Vec<u8>>>

pub fn from_cert_chain<B: AsRef<[u8]>>( first: &B, rest: &[B] ) -> Result<(Writecap, AsymKeyPub<Sign>)>

impl Writecap

pub fn assert_valid_for(&self, path: &BlockPath) -> Result<()>

Verifies that the given Writecap actually grants permission to write to the given BlockPath.

impl Writecap

pub fn root_signing_key(&self) -> &AsymKeyPub<Sign>

Returns the root key that was used to sign this writecap.

pub fn issued_to(&self) -> &Principal

pub fn expires(&self) -> Epoch

Returns the Epoch representing the instant when this writecap expires.

pub fn root_principal(&self) -> Principal

Returns the principal of the root key which was used to sign this writecap.

pub fn root_block_path(&self) -> BlockPath

Returns the path to the root block of the blocktree that the root principal owns.

pub fn path(&self) -> &BlockPath

Returns a reference to the path contained in this Writecap.

pub fn bind_path(&self) -> BlockPath

Returns the path that the Principal this Writecap was issued to is allowed to bind.

pub fn assert_issued_to(&self, principal: &Principal) -> Result<()>

Returns Ok if and only if this Writecap was issued to principal.

Trait Implementations

impl Clone for Writecap

fn clone(&self) -> Writecap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Writecap

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Writecap

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<Writecap> for Writecap

fn eq(&self, other: &Writecap) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Writecap

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
