Enum CloseReason 

pub enum CloseReason {
    None,
    Graceful,
    Aborted,
}

Reason for connection closure - distinguishes FIN vs RST semantics.

In real TCP:

• FIN (graceful close): Peer gets EOF on read, writes may still work briefly
• RST (aborted close): Peer gets ECONNRESET immediately on both read and write

Variants

None

Connection is not closed

Graceful

Graceful close (FIN) - peer will get EOF on read

Aborted

Aborted close (RST) - peer will get ECONNRESET

Trait Implementations

impl Clone for CloseReason

fn clone(&self) -> CloseReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CloseReason

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

Formats the value using the given formatter.

impl Default for CloseReason

fn default() -> CloseReason

Returns the “default value” for a type.

impl PartialEq for CloseReason

fn eq(&self, other: &CloseReason) -> 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 Copy for CloseReason

impl Eq for CloseReason

impl StructuralPartialEq for CloseReason
