Struct CpuGrid 

pub struct CpuGrid {
    pub core_usage: Vec<f64>,
    /* private fields */
}

Per-core CPU grid with gradient-colored meters.

Fields

core_usage: Vec<f64>

Per-core utilization (0.0-100.0).

Implementations

impl CpuGrid

pub fn new(core_usage: Vec<f64>) -> Self

Create a new CPU grid with core usage data.

pub fn with_gradient(self, gradient: Gradient) -> Self

Set the gradient for coloring.

pub fn with_columns(self, cols: usize) -> Self

Set explicit column count.

pub fn compact(self) -> Self

Enable compact mode (minimal spacing).

pub fn without_labels(self) -> Self

Disable core labels.

pub fn with_percentages(self) -> Self

Show numeric percentages instead of meter characters. Format: “12 45%” or “ 5 99%“ (like ttop).

pub fn with_freq_indicators(self) -> Self

Enable frequency scaling indicators (⚡↑→↓·).

Requires frequencies to be set via with_frequencies(). Indicators show scaling state:

• ⚡ Turbo (>100% of base)
• ↑ High (80-100% of max)
• → Normal (50-80% of max)
• ↓ Scaled (20-50% of max)
• · Idle (<20% of max)

pub fn with_frequencies(self, current: Vec<u32>, max: Vec<u32>) -> Self

Set per-core frequency data (current and max frequencies in MHz).

Both vectors should have the same length as core_usage.

pub fn with_governor(self, governor: CpuGovernor) -> Self

Set the CPU governor (affects display title/info).

pub fn set_usage(&mut self, usage: Vec<f64>)

Update core usage data.

pub fn set_frequencies(&mut self, current: Vec<u32>, max: Vec<u32>)

Update frequency data.

pub fn set_governor(&mut self, governor: CpuGovernor)

Update CPU governor.

pub fn governor(&self) -> Option<&CpuGovernor>

Get the current CPU governor, if set.

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

Get the governor display string for UI titles.

pub fn core_count(&self) -> usize

Get the number of cores.

pub fn avg_frequency_ghz(&self) -> Option<f64>

Get the average frequency across all cores in GHz.
