Crate gander_core 

gander-core — platform data collection and process model.

This crate must not depend on any UI crate. That keeps the parsers testable against fixtures on any host, and makes a --json batch mode (and future non-TUI front ends) nearly free.

Two backends exist:

• linux — reads /proc and /sys. Parametrised by a root path, so the entire read path is testable from fixtures on any unix.
• [darwin] — uses libproc, sysctl and Mach host statistics.

Both produce the same row::Row / system::SystemSnapshot types, so the UI and configuration layers are platform-independent.

See docs/DESIGN.md and docs/PORTABILITY.md.

Re-exports

pub use linux::LinuxPlatform as CurrentPlatform;

Modules

action

Process actions.

affinity

CPU affinity: which cores a process may run on.

capability

Platform capabilities that vary per OS, resolved at compile time.

format

Human-readable formatting.

linux

The /proc backend. Compiles on any unix because the IO layer is parameterised by a root path; only Linux has a live /proc to point it at. Linux /proc and /sys access.

row

Field identifiers and their presentation metadata.

system

System-wide snapshots: CPU, memory, swap, load, uptime.

table

The process table: scan, cache, derive, sort, filter.

tree

Tree-view construction.

users

uid to user-name resolution.

Structs

ScanOptions

What the front end is currently showing, and therefore what the sampler has to pay for.

Constants

PLATFORM_SUPPORTED

Whether a live backend exists for this build.

Traits

PlatformSampler

A unified sampler interface so the front end does not name a backend.

Type Aliases

Pid

Process identifier.

Sampler

The sampler for the current target.
