The standard library contains the core modules that most Thrust programs use for everyday work: input and output, memory management, math helpers, dynamic arrays, and C bindings. It is intentionally small and explicit, so each module keeps close to the behavior it exposes.
These pages describe what each module provides, how its functions are meant to be used, and which parts map directly to C library behavior. Use this section as the starting point when you need reusable building blocks before writing lower-level bindings yourself.
std::math
Mathematical constants and wrappers around scalar math functions for f64 and f32.
std::mem
Allocation, reallocation, memory copy/move/set helpers, and memory mapping constants.
std::collections::vector
Generic contiguous dynamic array with capacity growth and index-based operations.
std::tstring
Owned null-terminated strings with byte operations, UTF-8 validation, and Unicode code point helpers.
std::ffi::c
Type aliases, constants, and C ABI signatures used by standard wrappers.
std::optional
Optional value container with presence checks and safe access.
std::env
Process arguments, environment variables, and common system paths.
std::int
Parsing of signed and unsigned integers from text.
std::float
Parsing of floating-point values from text.
std::random
Random numbers and buffer filling.
std::collections::stack
Last-in first-out container.
std::collections::queue
First-in first-out container.
std::collections::vecdeque
Double-ended queue with push and pop on both ends.
std::collections::hashmap
Hash map from keys to values.
std::collections::hashset
Hash set of keys.
std::intrinsics::int
Integer intrinsics: overflow checks, saturation, and bit operations.
std::intrinsics::float
Floating-point intrinsics: abs, min, max, sqrt, fused multiply-add.
std::ffi::c::env
Raw C bindings for environment access.
std::ffi::c::int
Raw C bindings for integer text conversion.
std::ffi::c::float
Raw C bindings for floating-point text conversion.
std::ffi::c::random
