Crate arrow2[−][src]
Re-exports
pub use alloc::total_allocated_bytes;Modules
Defines memory-related functions, such as allocate/deallocate/reallocate memory regions, cache and allocation alignments.
This module contains arrays: fixed-length and immutable containers with optional values
that are layed in memory according to the Arrow specification.
Each array type has its own struct. The following are the main array types:
Contains efficient containers of booleans: Bitmap and MutableBitmap.
The memory backing these containers is cache-aligned and optimized for both vertical
and horizontal operations over booleans.
This module contains core functionality to handle memory in this crate.
Contains operators over arrays. This module’s general design is
that each operator has two interfaces, a statically-typed version and a dynamically-typed
version.
The statically-typed version expects concrete arrays (like PrimitiveArray);
the dynamically-typed version expects &dyn Array and errors if the the type is not
supported.
Some dynamically-typed operators have an auxiliary function, can_*, that returns
true if the operator can be applied to the particular DataType.
This module contains logical types defined in the Arrow specification:
Defines ArrowError, representing all errors returned by this crate.
Contains interfaces to use the C Data Interface.
A two-dimensional batch of column-oriented data with a defined schema.
Conversion methods for dates and times.
This module contains traits to handle all physical types used in this crate.
Most physical types used in this crate are native Rust types, like i32.
The most important trait is NativeType, implemented for all Arrow types
with a Rust correspondence (such as i32 or f64).
