Struct rocksdb::PrefixRange

pub struct PrefixRange<K>(pub K);

Expand description

Representation of a range of keys starting with given prefix.

Can be used as argument of crate::ReadOptions::set_iterate_range method to set iterate bounds.

Trait Implementations§

impl<K: Clone> Clone for PrefixRange<K>

fn clone(&self) -> PrefixRange<K>

Returns a copy of the value. Read more

1.0.0 · source§

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

Performs copy-assignment from source. Read more

impl<K: Into<Vec<u8>>> IterateBounds for PrefixRange<K>

fn into_bounds(self) -> (Option<Vec<u8>>, Option<Vec<u8>>)

Converts the prefix range representation into pair of bounds.

The conversion assumes lexicographical sorting on u8 values. For example, PrefixRange("a") is equivalent to "a".."b" range. Note that for some prefixes, either of the bounds may be None. For example, an empty prefix is equivalent to a full range (i.e. both bounds being None).
