pub struct MockSpawner { /* private fields */ }Expand description
Test ProcessSpawner that returns scripted MockProcess handles
and captures the SpawnSpec passed to each spawn.
Implementations§
Source§impl MockSpawner
impl MockSpawner
Sourcepub fn new() -> Self
pub fn new() -> Self
Build an empty spawner. Call Self::enqueue to script behaviour
for each anticipated spawn.
Sourcepub fn enqueue(&self, config: MockProcessConfig) -> MockHandleController
pub fn enqueue(&self, config: MockProcessConfig) -> MockHandleController
Enqueue a configuration for the next spawn. Returns a controller
that lets the test drive the resulting MockProcess state
(append stdout, complete with status, etc.). For one-shot
foreground tests, the controller may simply be dropped.
Sourcepub fn captured(&self) -> Vec<SpawnSpec>
pub fn captured(&self) -> Vec<SpawnSpec>
Returns the SpawnSpec objects captured so far, in order.
Sourcepub fn last_controller(&self) -> Option<MockHandleController>
pub fn last_controller(&self) -> Option<MockHandleController>
Returns the latest controller installed via Self::enqueue.
Convenience for tests that only enqueue one config.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
