Enum IntVectorFormat 

pub enum IntVectorFormat {
    Java,
    Epserde,
    BitFieldVec,
    Ascii,
    Json,
}

How to store vectors of integers.

Variants

Java

Java-compatible format: a sequence of big-endian longs (64 bits).

Epserde

A slice of usize serialized using ε-serde.

BitFieldVec

A BitFieldVec stored using ε-serde. It stores each element using ⌊log₂(max)⌋ + 1 bits. It requires to allocate the BitFieldVec in RAM before serializing it.

Ascii

ASCII format, one integer per line.

Json

A JSON Array.

Implementations

impl IntVectorFormat

pub fn store( &self, path: impl AsRef<Path>, data: &[u64], max: Option<u64>, ) -> Result<()>

Stores a vector of u64 in the specified path`` using the format defined by self`.

max is the maximum value of the vector. If it is not provided, it will be computed from the data.

pub fn store_usizes( &self, path: impl AsRef<Path>, data: &[usize], max: Option<usize>, ) -> Result<()>

Stores a vector of usize in the specified path using the format defined by self. max is the maximum value of the vector, if it is not provided, it will be computed from the data.

This helper method is available only on 64-bit architectures as Java’s format uses of 64-bit integers.

Trait Implementations
