Struct Progress 

pub struct Progress { /* private fields */ }

Counter shared between a reference algorithm (which bumps it) and a caller (which polls it for streaming progression).

Implementations

impl Progress

pub fn new() -> Self

Empty progress with total = 0. The reference algorithm will set the real total via Self::set_total once it knows the problem shape.

pub fn with_total(total: u64) -> Self

Pre-declared total: caller already knows the count and just wants to poll. References still call Self::set_total on entry, which is a no-op when the value matches.

pub fn set_total(&self, total: u64)

Declare the total number of output writes. Called by the reference algorithm at entry, before the first Self::bump.

pub fn bump(&self)

Increment the counter by one output write.

pub fn bump_by(&self, n: u64)

Increment the counter by n output writes — useful when a reference writes a contiguous run of outputs in one inner loop.

pub fn total(&self) -> u64

pub fn current(&self) -> u64

pub fn fraction(&self) -> f64

current / total clamped to [0.0, 1.0]. Returns 0.0 when total is zero (reference hasn’t started or declared its total yet).

Trait Implementations

impl Debug for Progress

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Progress

fn default() -> Self

Returns the “default value” for a type.
