Struct anise::structure::lookuptable::LookUpTable

pub struct LookUpTable<const ENTRIES: usize> {
    pub by_id: FnvIndexMap<i32, Entry, ENTRIES>,
    pub by_name: FnvIndexMap<String<32>, Entry, ENTRIES>,
}

A LookUpTable allows finding the Entry associated with either an ID or a name.

Note

Both the IDs and the name MUST be unique in the look up table.

Fields

by_id: FnvIndexMap<i32, Entry, ENTRIES>

Unique IDs of each item in the

by_name: FnvIndexMap<String<32>, Entry, ENTRIES>

Corresponding index for each hash

Implementations

impl<const ENTRIES: usize> LookUpTable<ENTRIES>

pub fn append( &mut self, id: i32, name: &str, entry: Entry ) -> Result<(), LutError>

pub fn append_id(&mut self, id: i32, entry: Entry) -> Result<(), LutError>

pub fn append_name(&mut self, name: &str, entry: Entry) -> Result<(), LutError>

pub fn entries( &self ) -> FnvIndexMap<Entry, (Option<i32>, Option<String<32>>), ENTRIES>

Returns the list of entries of this LUT

Trait Implementations

impl<const ENTRIES: usize> Clone for LookUpTable<ENTRIES>

fn clone(&self) -> LookUpTable<ENTRIES>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const ENTRIES: usize> Debug for LookUpTable<ENTRIES>

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

Formats the value using the given formatter.

impl<'a, const ENTRIES: usize> Decode<'a> for LookUpTable<ENTRIES>

fn decode<R: Reader<'a>>(decoder: &mut R) -> Result<Self>

Attempt to decode this message using the provided decoder.

fn from_der(bytes: &'a [u8]) -> Result<Self, Error>

Parse Self from the provided DER-encoded byte slice.

impl<const ENTRIES: usize> Default for LookUpTable<ENTRIES>

fn default() -> LookUpTable<ENTRIES>

Returns the “default value” for a type.

impl<const ENTRIES: usize> Encode for LookUpTable<ENTRIES>

fn encoded_len(&self) -> Result<Length>

Compute the length of this value in bytes when encoded as ASN.1 DER.

fn encode(&self, encoder: &mut impl Writer) -> Result<()>

Encode this value as ASN.1 DER using the provided Writer.

fn encode_to_slice<'a>(&self, buf: &'a mut [u8]) -> Result<&'a [u8], Error>

Encode this value to the provided byte slice, returning a sub-slice containing the encoded message.

fn encode_to_vec(&self, buf: &mut Vec<u8>) -> Result<Length, Error>

Encode this message as ASN.1 DER, appending it to the provided byte vector.

fn to_der(&self) -> Result<Vec<u8>, Error>

Encode this type as DER, returning a byte vector.

impl<const ENTRIES: usize> PartialEq for LookUpTable<ENTRIES>

fn eq(&self, other: &LookUpTable<ENTRIES>) -> 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.
