Enum RequestSentStatus 

#[non_exhaustive]
pub enum RequestSentStatus {
    Sent,
    NotSent,
    Unknown,
}

Tri-state indicating whether a request was sent on the wire.

This is critical for retry decisions:

• Sent: The request was definitely transmitted; non-idempotent operations should not be retried without additional safeguards (etag checks).
• NotSent: The request definitely was NOT transmitted; safe to retry.
• Unknown: Cannot determine if request was sent; treat as potentially sent for safety (don’t retry non-idempotent operations).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Sent

Request was definitely sent on the wire. This is confirmed when we receive response headers or the transport completes successfully.

NotSent

Request was definitely NOT sent on the wire. This is confirmed for errors that occur before transmission (e.g., DNS resolution failure, connection refused).

Unknown

Cannot determine if request was sent. Treat as potentially sent for retry safety.

Implementations

impl RequestSentStatus

pub fn may_have_been_sent(&self) -> bool

Returns true if the request may have been sent.

This is conservative: returns true for both Sent and Unknown, since we must assume Unknown might have been sent for retry safety.

pub fn definitely_sent(&self) -> bool

Returns true if we know for certain the request was sent.

pub fn definitely_not_sent(&self) -> bool

Returns true if we know for certain the request was NOT sent.

pub fn as_str(&self) -> &'static str

Returns the string representation of this request sent status.

Trait Implementations

impl AsRef<str> for RequestSentStatus

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for RequestSentStatus

fn clone(&self) -> RequestSentStatus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RequestSentStatus

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

Formats the value using the given formatter.

impl Default for RequestSentStatus

fn default() -> RequestSentStatus

Returns the “default value” for a type.

impl Display for RequestSentStatus

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

Formats the value using the given formatter.

impl PartialEq for RequestSentStatus

fn eq(&self, other: &RequestSentStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RequestSentStatus

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RequestSentStatus
