#[non_exhaustive]pub enum AccountJiraIssueManagementStatus {
Disabled,
Enabled,
Unknown(UnknownVariantValue),
}Expand description
When writing a match expression against AccountJiraIssueManagementStatus, it is important to ensure
your code is forward-compatible. That is, if a match arm handles a case for a
feature that is supported by the service but has not been represented as an enum
variant in a current version of SDK, your code should continue to work when you
upgrade SDK to a future version in which the enum does include a variant for that
feature.
Here is an example of how you can make a match expression forward-compatible:
# let accountjiraissuemanagementstatus = unimplemented!();
match accountjiraissuemanagementstatus {
AccountJiraIssueManagementStatus::Disabled => { /* ... */ },
AccountJiraIssueManagementStatus::Enabled => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}The above code demonstrates that when accountjiraissuemanagementstatus represents
NewFeature, the execution path will lead to the second last match arm,
even though the enum does not contain a variant AccountJiraIssueManagementStatus::NewFeature
in the current version of SDK. The reason is that the variable other,
created by the @ operator, is bound to
AccountJiraIssueManagementStatus::Unknown(UnknownVariantValue("NewFeature".to_owned()))
and calling as_str on it yields "NewFeature".
This match expression is forward-compatible when executed with a newer
version of SDK where the variant AccountJiraIssueManagementStatus::NewFeature is defined.
Specifically, when accountjiraissuemanagementstatus represents NewFeature,
the execution path will hit the second last match arm as before by virtue of
calling as_str on AccountJiraIssueManagementStatus::NewFeature also yielding "NewFeature".
Explicitly matching on the Unknown variant should
be avoided for two reasons:
- The inner data
UnknownVariantValueis opaque, and no further information can be extracted. - It might inadvertently shadow other intended match arms.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Disabled
Enabled
Unknown(UnknownVariantValue)
Unknown. See the docs on this enum for the correct way to handle unknown variants.Unknown contains new variants that have been added since this code was generated.

impl AccountJiraIssueManagementStatus
Sourcepub fn try_parse(value: &str) -> Result<Self, UnknownVariantError>
pub fn try_parse(value: &str) -> Result<Self, UnknownVariantError>

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().

builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.

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

use yansi::{Paint, Attribute};

wrap(), which have the same functionality but are
pithier.
§Example

Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.

§Example
Enable styling painted only when both stdout and stderr are TTYs:
