Struct MockFormatter 

pub struct MockFormatter { /* private fields */ }

A deterministic in-memory Formatter for tests — no real device is ever touched. Mirrors MockSshAgent: construct it with a canned DeviceInfo, then inspect what erase recorded.

Implementations

impl MockFormatter

pub fn new(info: DeviceInfo) -> Self

A formatter whose probe returns info (with the queried node overlaid) and whose erase succeeds and records its arguments. list_devices returns just info.

pub fn swapping(first: DeviceInfo, second: DeviceInfo) -> Self

A formatter that probes as first, then (from the second probe onward) reports second on the same node — to exercise the TOCTOU re-probe guard.

pub fn with_devices(devices: Vec<DeviceInfo>) -> Self

A formatter whose list_devices returns devices (probe still returns the first as the canned info) — to test the candidate-listing/filtering.

pub fn failing(info: DeviceInfo) -> Self

Like Self::new, but erase fails — to test that a format error propagates after an approval.

pub fn erased(&self) -> Option<(String, String)>

The (node, label) the last successful erase recorded, if any.

Trait Implementations

impl Formatter for MockFormatter

fn probe(&self, node: &str) -> Result<DeviceInfo, CoreError>

Inspect a device without modifying it.

fn list_devices(&self) -> Result<Vec<DeviceInfo>, CoreError>

Enumerate whole physical devices the user could pick to format — the raw probe list (the CLI applies eligible_targets to offer only the safe ones). Read-only.

fn erase(&self, node: &str, label: &str) -> Result<(), CoreError>

Erase the device and lay down a single empty volume named label. Destructive. Never call this directly — go through format_removable, which enforces the safety rails and the broker gate.
