Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.attributes: Option<HashMap<String, String>>
A map of the topic's attributes. Attributes in this map include the following:
-
DeliveryPolicy
– The JSON serialization of the topic's delivery policy. -
DisplayName
– The human-readable name used in theFrom
field for notifications toemail
andemail-json
endpoints. -
EffectiveDeliveryPolicy
– The JSON serialization of the effective delivery policy, taking system defaults into account. -
Owner
– The Amazon Web Services account ID of the topic's owner. -
Policy
– The JSON serialization of the topic's access control policy. -
SignatureVersion
– The signature version corresponds to the hashing algorithm used while creating the signature of the notifications, subscription confirmations, or unsubscribe confirmation messages sent by Amazon SNS.-
By default,
SignatureVersion
is set to 1. The signature is a Base64-encoded SHA1withRSA signature. -
When you set
SignatureVersion
to 2. Amazon SNS uses a Base64-encoded SHA256withRSA signature.If the API response does not include the
SignatureVersion
attribute, it means that theSignatureVersion
for the topic has value 1.
-
-
SubscriptionsConfirmed
– The number of confirmed subscriptions for the topic. -
SubscriptionsDeleted
– The number of deleted subscriptions for the topic. -
SubscriptionsPending
– The number of subscriptions pending confirmation for the topic. -
TopicArn
– The topic's ARN. -
TracingConfig
– Tracing mode of an Amazon SNS topic. By defaultTracingConfig
is set toPassThrough
, and the topic passes through the tracing header it receives from an Amazon SNS publisher to its subscriptions. If set toActive
, Amazon SNS will vend X-Ray segment data to topic owner account if the sampled flag in the tracing header is true. This is only supported on standard topics.
The following attribute applies only to server-side-encryption:
-
KmsMasterKeyId
- The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms. For more examples, see KeyId in the Key Management Service API Reference.
The following attributes apply only to FIFO topics:
-
ArchivePolicy
– The policy that sets the retention period for messages stored in the message archive of an Amazon SNS FIFO topic. -
BeginningArchiveTime
– The earliest starting point at which a message in the topic’s archive can be replayed from. This point in time is based on the configured message retention period set by the topic’s message archiving policy. -
ContentBasedDeduplication
– Enables content-based deduplication for FIFO topics.-
By default,
ContentBasedDeduplication
is set tofalse
. If you create a FIFO topic and this attribute isfalse
, you must specify a value for theMessageDeduplicationId
parameter for the Publish action. -
When you set
ContentBasedDeduplication
totrue
, Amazon SNS uses a SHA-256 hash to generate theMessageDeduplicationId
using the body of the message (but not the attributes of the message).(Optional) To override the generated value, you can specify a value for the
MessageDeduplicationId
parameter for thePublish
action.
-
-
FifoTopic
– When this is set totrue
, a FIFO topic is created.

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();

, which have the same functionality but

§Example
Set background color to red using fg()

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();

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();

👎Deprecated since 1.0.1: renamed to resetting()

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);
