Struct DeviceInfo 

pub struct DeviceInfo {
    pub node: String,
    pub name: String,
    pub total_bytes: u64,
    pub used_bytes: Option<u64>,
    pub removable: bool,
    pub ejectable: bool,
    pub internal: bool,
    pub boot: bool,
    pub mounted: bool,
}

What the OS reports about a candidate device, authored by Formatter::probe — never from user input. Carries no secret material (I12).

Fields

node: String

The device node as the OS addresses it (e.g. /dev/disk4).

name: String

Human label (volume / media name), best-effort; may be empty.

total_bytes: u64

Total capacity in bytes (0 if the OS did not report it).

used_bytes: Option<u64>

Bytes in use across mounted volumes, if the OS reported it.

removable: bool

The device’s media is removable from its mechanism (SD card, optical), as opposed to fixed flash/SSD. Informational only — it is NOT the erase safety predicate (a USB SSD reports Fixed yet is a perfectly safe, intended target). The rail keys on Self::ejectable + external instead.

ejectable: bool

The device can be ejected from the running system (external bus). Internal disks are not ejectable. This — together with not-internal and not-boot — is the actual erase-safety predicate the rail enforces.

internal: bool

The device is internal/onboard — the opposite of an external stick.

boot: bool

The device backs the current boot/system volume.

mounted: bool

At least one volume on the device is currently mounted.

Implementations

impl DeviceInfo

pub fn human_size(&self) -> String

A human-readable capacity for the I16 headline (never a value).

pub fn non_empty(&self) -> bool

Whether the device appears to hold data — used to decide whether the confirmation headline must carry a content warning.

Trait Implementations

impl Clone for DeviceInfo

fn clone(&self) -> DeviceInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DeviceInfo

impl PartialEq for DeviceInfo

fn eq(&self, other: &DeviceInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
