Struct GlobalDefault 

pub struct GlobalDefault { /* private fields */ }

A global default f64 value with atomic access.

This type provides thread-safe access to a global default value, typically used for tolerance parameters like rtol.

Example

use tensor4all_core::GlobalDefault;

static MY_DEFAULT: GlobalDefault = GlobalDefault::new(1e-12);

// Get the default value
let rtol = MY_DEFAULT.get();

// Set a new default value
MY_DEFAULT.set(1e-10).unwrap();

Implementations

impl GlobalDefault

pub const fn new(initial: f64) -> Self

Create a new global default with the given initial value.

This is a const fn, so it can be used in static declarations.

pub fn get(&self) -> f64

Get the current default value.

pub fn set(&self, value: f64) -> Result<(), InvalidRtolError>

Set a new default value.

Errors

Returns InvalidRtolError if the value is not finite or is negative.

pub fn set_unchecked(&self, value: f64)

Set a new default value without validation.

Safety

The caller must ensure the value is valid (finite and non-negative).
