Struct Fp 

pub struct Fp([u8; 32]);

A 32-byte BLAKE3 content fingerprint used as the primary key for books.

Serialized as a 64-character lowercase hex string (e.g. "af1349b9f5f9a1a6a0404dea36dcc949...").

Tuple Fields

0: [u8; 32]

Implementations

impl Fp

pub(crate) fn from_legacy_str(s: &str) -> Result<Self, FpParseError>

Parses a legacy 16-character uppercase hex fingerprint (mtime + size metadata format) into an Fp.

The u64 value is stored in the last 8 bytes (big-endian); the remaining 24 bytes are zero. This matches the from_u64 layout so that legacy entries round-trip consistently. V2 migration will re-key these to real BLAKE3 hashes once the files are found on disk.

Trait Implementations

impl Clone for Fp

fn clone(&self) -> Fp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fp

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

Formats the value using the given formatter.

impl<'r> Decode<'r, Sqlite> for Fp

fn decode(value: SqliteValueRef<'r>) -> Result<Self, BoxDynError>

Decode a new value of this type using a raw value from the database.

impl<'de> Deserialize<'de> for Fp

fn deserialize<D>(deserializer: D) -> Result<Fp, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Fp

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

Formats the value using the given formatter.

impl<'q> Encode<'q, Sqlite> for Fp

fn encode_by_ref( &self, buf: &mut Vec<SqliteArgumentValue<'q>>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

fn size_hint(&self) -> usize

impl FromStr for Fp

type Err = FpParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Fp

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Fp

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Fp

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Type<Sqlite> for Fp

fn type_info() -> SqliteTypeInfo

impl Deref for Fp

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Copy for Fp

impl Eq for Fp

impl StructuralPartialEq for Fp
