Struct 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 value(&self, row: NonZero<u32>) -> Option<&[u8]>

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

unsafe fn value_unchecked(&self, row: NonZero<u32>) -> &[u8]

Returns the value of the specified row.

unsafe fn node_value_unchecked( &self, row: NonZero<u32>, ) -> (&AvltrieeNode<DataAddress>, &[u8])

Returns node and value of the specified row.

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

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

Search row of a value.

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

Finds the edge of a node from the specified value.

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

Search >= value.

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

Search <= value.

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

Search > value.

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

Search < value.

fn range(&self, start_value: &I, end_value: &I) -> Option<Range<NonZero<u32>>>

Search with range value with custom ord.

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 insert(&mut self, value: &I) -> NonZero<u32>

where T: Clone,

Creates a new row and assigns a value to it.

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.
