Struct BatchData 

pub struct BatchData {
    pub instances: Vec<Arc<str>>,
    pub input_paths: Vec<Arc<str>>,
    pub indexes: Vec<usize>,
}

Data structure for holding batched input data.

This struct contains the instances, input paths, and indexes for a batch of data. It’s used in the OCR pipeline to process multiple inputs together for efficiency.

Fields

instances: Vec<Arc<str>>

The instances in the batch, stored as Arc<str> for efficient sharing.

input_paths: Vec<Arc<str>>

The input paths for the instances in the batch, stored as Arc<str> for efficient sharing.

indexes: Vec<usize>

The indexes of the instances in the original data set.

Implementations

impl BatchData

pub fn from_shared_arc_paths(paths: Vec<Arc<str>>, indexes: Vec<usize>) -> Self

Creates a new BatchData instance from shared Arc<str> paths and indexes.

Arguments

• paths - A vector of Arc<str> representing the paths to the instances.
• indexes - A vector of usize representing the indexes of the instances in the original data set.

Returns

A new BatchData instance.

pub fn len(&self) -> usize

Returns the number of instances in the batch.

Returns

The number of instances in the batch.

pub fn is_empty(&self) -> bool

Checks if the batch is empty.

Returns

True if the batch is empty, false otherwise.

pub fn instances_as_str(&self) -> impl Iterator<Item = &str> + '_

Returns an iterator over the instances as string slices.

Returns

An iterator over the instances as string slices.

pub fn input_paths_as_str(&self) -> impl Iterator<Item = &str> + '_

Returns an iterator over the input paths as string slices.

Returns

An iterator over the input paths as string slices.
