Enum Side 

#[repr(u8)]
pub enum Side {
    Source = 0,
    Destination = 1,
}

Which side of an operation a probe is on.

Tools like rcp and rcmp touch two filesystems with different service-time profiles; we run an independent controller per side so a saturated source doesn’t drag the destination’s cwnd down or vice versa. Single-path tools (rrm, filegen) still partition reads (Source) from writes/mutations (Destination) since those have different latency profiles even on the same filesystem.

Variants

Source = 0

Reads of the source filesystem — directory walks, source-side stats.

Destination = 1

Writes/mutations of the destination filesystem — create_dir, hard_link, unlink, open(O_CREAT), etc.

Implementations

impl Side

pub const ALL: [Self; 2]

All side variants, in discriminant order.

Trait Implementations

impl Clone for Side

fn clone(&self) -> Side

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Side

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

Formats the value using the given formatter.

impl Hash for Side

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Side

fn eq(&self, other: &Side) -> 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.
