Struct BlockDevices 

pub struct BlockDevices {
    pub blockdevices: Vec<BlockDevice>,
}

Represents the entire JSON output produced by lsblk --json.

Fields

blockdevices: Vec<BlockDevice>

A vector of block devices.

Implementations

impl BlockDevices

pub fn len(&self) -> usize

Returns the number of top-level block devices.

pub fn is_empty(&self) -> bool

Returns true if there are no block devices.

pub fn iter(&self) -> Iter<'_, BlockDevice>

Returns an iterator over references to the block devices.

pub fn system(&self) -> Vec<&BlockDevice>

Returns a vector of references to BlockDevice entries that have a mountpoint of / on them or on any of their recursive children.

pub fn non_system(&self) -> Vec<&BlockDevice>

Returns a vector of references to BlockDevice entries that do not have a mountpoint of / on them or on any of their recursive children.

pub fn find_by_name(&self, name: &str) -> Option<&BlockDevice>

Finds a top-level block device by name.

Returns None if no device with the given name exists.

Trait Implementations

impl Clone for BlockDevices

fn clone(&self) -> BlockDevices

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockDevices

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

Formats the value using the given formatter.

impl Default for BlockDevices

fn default() -> BlockDevices

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlockDevices

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> IntoIterator for &'a BlockDevices

type Item = &'a BlockDevice

The type of the elements being iterated over.

type IntoIter = Iter<'a, BlockDevice>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for BlockDevices

type Item = BlockDevice

The type of the elements being iterated over.

type IntoIter = IntoIter<BlockDevice>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for BlockDevices

fn eq(&self, other: &BlockDevices) -> 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.

impl Serialize for BlockDevices

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
