Struct MemoryBar 

pub struct MemoryBar { /* private fields */ }

Stacked memory bar with labeled segments.

Implementations

impl MemoryBar

pub fn new(total_bytes: u64) -> Self

Create a new memory bar with total bytes.

pub fn from_usage( used_bytes: u64, cached_bytes: u64, swap_used: u64, swap_total: u64, total_bytes: u64, ) -> Self

Create from common memory info values.

pub fn add_segment(&mut self, segment: MemorySegment)

Add a segment.

pub fn segment(self, name: impl Into<String>, bytes: u64, color: Color) -> Self

Add a segment (builder pattern for chaining).

pub fn with_bar_width(self, width: usize) -> Self

Set bar width.

pub fn without_labels(self) -> Self

When enabled, huge pages are displayed as an additional row/indicator.

pub fn show_huge_pages(self, show: bool) -> Self

Enable/disable huge pages display.

pub fn set_huge_pages(&mut self, huge_pages: HugePages)

Update huge pages data.

pub fn huge_pages(&self) -> Option<&HugePages>

Get huge pages statistics, if set.

pub fn has_huge_pages(&self) -> bool

Check if huge pages are configured and being tracked.

pub fn set_total(&mut self, total: u64)

Update total bytes.

pub fn total(&self) -> u64

Get total bytes.

pub fn used(&self) -> u64

Get used bytes (sum of all segments).

pub fn usage_percent(&self) -> f64

Get usage percentage.
