Struct TierStatus

Source

pub struct TierStatus {
    pub kind: TierKind,
    pub capacity_bytes: u64,
    pub used_bytes: u64,
    pub target_ratio: f64,
}

Expand description

Live utilization snapshot for a single storage tier.

Fields§

§kind: TierKind

Which tier this status belongs to.

§capacity_bytes: u64

Total capacity of the tier in bytes.

§used_bytes: u64

Number of bytes currently in use.

§target_ratio: f64

Desired utilization ratio in [0.0, 1.0].

Implementations§

Source §

impl TierStatus

Source

pub fn utilization(&self) -> f64

Returns the current utilization ratio (used / capacity). Returns 0.0 when capacity_bytes is zero.

Source

pub fn free_bytes(&self) -> u64

Returns the number of bytes still available (capacity - used), saturating at zero.

Source

pub fn is_over_target(&self) -> bool

Returns true when the tier is above its target utilization ratio.

Source

pub fn excess_bytes(&self) -> u64

Returns how many bytes exceed the target usage level.

When the tier is at or below its target the result is 0.
