Struct versatile_data::IdxBinary

pub struct IdxBinary { /* private fields */ }

Implementations

impl IdxBinary

pub fn new<P>(directory: P, allocation_lot: u32) -> IdxBinary

where P: AsRef<Path>,

Opens the file and creates the IdxBinary.

Arguments

• path - Path of directory to save data.
• allocation_lot - Extends the specified size when the file size becomes insufficient due to data addition. If you expect to add a lot of data, specifying a larger size will improve performance.

pub fn new_ext<P>(path: P, allocation_lot: u32) -> IdxBinary

where P: AsRef<Path>,

Opens the file and creates the IdxBinary. /// # Arguments

• path - Path of part of filename without extension to save data.
• allocation_lot - Extends the specified size when the file size becomes insufficient due to data addition. If you expect to add a lot of data, specifying a larger size will improve performance.

pub fn row_or_insert(&mut self, content: &[u8]) -> NonZero<u32>

Finds a sequence of bytes, inserts it if it doesn’t exist, and returns a row.

Trait Implementations

impl AsMut<Avltriee<DataAddress, [u8], IdxFileAllocator<DataAddress>>> for IdxBinary

fn as_mut( &mut self ) -> &mut Avltriee<DataAddress, [u8], IdxFileAllocator<DataAddress>>

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Avltriee<DataAddress, [u8], IdxFileAllocator<DataAddress>>> for IdxBinary

fn as_ref(&self) -> &Avltriee<DataAddress, [u8], IdxFileAllocator<DataAddress>>

Converts this type into a shared reference of the (usually inferred) input type.

impl AvltrieeSearch<DataAddress, [u8], IdxFileAllocator<DataAddress>> for IdxBinary

fn cmp(left: &[u8], right: &[u8]) -> Ordering

fn invert<'a>(&'a self, value: &'a DataAddress) -> &'a [u8]

fn edge(&self, value: &I) -> (Option<NonZero<u32>>, Ordering)

Finds the edge of a node from the specified value.

fn row(&self, value: &I) -> Option<NonZero<u32>>

Search row of a value.

fn value<'a>(&'a self, row: NonZero<u32>) -> Option<&'a I>

where A: 'a, T: 'a,

Returns the value of the specified row. Returns None if the row does not exist.

unsafe fn value_unchecked<'a>(&'a self, row: NonZero<u32>) -> &'a I

where A: 'a, T: 'a,

Returns the value of the specified row.

impl AvltrieeUpdate<DataAddress, [u8], IdxFileAllocator<DataAddress>> for IdxBinary

fn convert_on_insert_unique(&mut self, input: &[u8]) -> DataAddress

fn on_delete(&mut self, row: NonZero<u32>)

fn update(&mut self, row: NonZero<u32>, value: &I)

where T: Clone,

Updates the value in the specified row.

fn delete(&mut self, row: NonZero<u32>)

Delete the specified row.
