Struct ProgressDrawTarget 

pub struct ProgressDrawTarget { /* private fields */ }

Target for draw operations

This tells a progress bar or a multi progress object where to paint to. The draw target is a stateful wrapper over a drawing destination and internally optimizes how often the state is painted to the output device.

Implementations

impl ProgressDrawTarget

pub fn stdout() -> ProgressDrawTarget

Draw to a buffered stdout terminal at a max of 15 times a second.

For more information see ProgressDrawTarget::to_term.

pub fn stderr() -> ProgressDrawTarget

Draw to a buffered stderr terminal at a max of 15 times a second.

This is the default draw target for progress bars. For more information see ProgressDrawTarget::to_term.

pub fn stdout_with_hz(refresh_rate: u64) -> ProgressDrawTarget

Draw to a buffered stdout terminal at a max of refresh_rate times a second.

For more information see ProgressDrawTarget::to_term.

pub fn stderr_with_hz(refresh_rate: u64) -> ProgressDrawTarget

Draw to a buffered stderr terminal at a max of refresh_rate times a second.

For more information see ProgressDrawTarget::to_term.

pub fn stdout_nohz() -> ProgressDrawTarget

Draw to a buffered stdout terminal without max framerate.

This is useful when data is known to come in very slowly and not rendering some updates would be a problem (for instance when messages are used extensively).

For more information see ProgressDrawTarget::to_term.

pub fn stderr_nohz() -> ProgressDrawTarget

Draw to a buffered stderr terminal without max framerate.

This is useful when data is known to come in very slowly and not rendering some updates would be a problem (for instance when messages are used extensively).

For more information see ProgressDrawTarget::to_term.

pub fn to_term( term: Term, refresh_rate: impl Into<Option<u64>>, ) -> ProgressDrawTarget

👎Deprecated since 0.16.0: Use ProgressDrawTarget::term instead

Draw to a terminal, optionally with a specific refresh rate.

Progress bars are by default drawn to terminals however if the terminal is not user attended the entire progress bar will be hidden. This is done so that piping to a file will not produce useless escape codes in that file.

Will panic if refresh_rate is Some(0). To disable rate limiting use None instead.

pub fn term( term: Term, refresh_rate: impl Into<Option<u64>>, ) -> ProgressDrawTarget

Draw to a terminal, optionally with a specific refresh rate.

Progress bars are by default drawn to terminals however if the terminal is not user attended the entire progress bar will be hidden. This is done so that piping to a file will not produce useless escape codes in that file.

Will panic if refresh_rate is Some(0). To disable rate limiting use None instead.

pub fn hidden() -> ProgressDrawTarget

A hidden draw target.

This forces a progress bar to be not rendered at all.

pub fn is_hidden(&self) -> bool

Returns true if the draw target is hidden.

This is internally used in progress bars to figure out if overhead from drawing can be prevented.
