Enum tink_proto::OutputPrefixType

#[repr(i32)]pub enum OutputPrefixType {
    UnknownPrefix,
    Tink,
    Legacy,
    Raw,
    Crunchy,
}

Tink produces and accepts ciphertexts or signatures that consist of a prefix and a payload. The payload and its format is determined entirely by the primitive, but the prefix has to be one of the following 4 types:

• Legacy: prefix is 5 bytes, starts with \x00 and followed by a 4-byte key id that is computed from the key material.
• Crunchy: prefix is 5 bytes, starts with \x00 and followed by a 4-byte key id that is generated randomly.
• Tink : prefix is 5 bytes, starts with \x01 and followed by 4-byte key id that is generated randomly.
• Raw : prefix is 0 byte, i.e., empty.

Variants

UnknownPrefix

Tink

Legacy

Raw

Crunchy

CRUNCHY is like LEGACY, but with two differences:

• Its key id is generated randomly (like TINK)
• Its signature schemes don't append zero to sign messages

Implementations

impl OutputPrefixType

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of OutputPrefixType.

pub fn from_i32(value: i32) -> Option<OutputPrefixType>

Converts an i32 to a OutputPrefixType, or None if value is not a valid variant.

Trait Implementations

impl Clone for OutputPrefixType

fn clone(&self) -> OutputPrefixType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for OutputPrefixType

impl Debug for OutputPrefixType

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

Formats the value using the given formatter.

fn default() -> OutputPrefixType

Returns the "default value" for a type.

impl Eq for OutputPrefixType

impl From<OutputPrefixType> for i32

fn from(value: OutputPrefixType) -> i32

impl Ord for OutputPrefixType

fn cmp(&self, other: &OutputPrefixType) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<OutputPrefixType> for OutputPrefixType

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<OutputPrefixType> for OutputPrefixType

fn partial_cmp(&self, other: &OutputPrefixType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool
