Struct GptPartitionEntryArrayLayout

pub struct GptPartitionEntryArrayLayout {
    pub start_lba: Lba,
    pub entry_size: GptPartitionEntrySize,
    pub num_entries: u32,
}

Disk layout of a GPT partition entry array.

Fields

start_lba: Lba

First block of the array.

entry_size: GptPartitionEntrySize

Size in bytes of each entry.

num_entries: u32

Number of entries in the array.

Implementations

impl GptPartitionEntryArrayLayout

pub fn num_blocks(&self, block_size: BlockSize) -> Option<u64>

Get the number of blocks needed for this layout. Returns None if overflow occurs.

pub fn num_blocks_as_usize(&self, block_size: BlockSize) -> Option<usize>

Get the number of blocks needed for this layout. Returns None if overflow occurs.

pub fn num_bytes_exact(&self) -> Option<u64>

Get the number of bytes needed for the entries in this layout, ignoring any padding needed at the end to match the block size. This corresponds to the number of bytes that are covered by the partition_entry_array_crc32.

Returns None if overflow occurs.

pub fn num_bytes_exact_as_usize(&self) -> Option<usize>

Get the number of bytes needed for the entries in this layout, ignoring any padding needed at the end to match the block size. This corresponds to the number of bytes that are covered by the partition_entry_array_crc32.

Returns None if overflow occurs.

pub fn num_bytes_rounded_to_block(&self, block_size: BlockSize) -> Option<u64>

Get the number of bytes needed for this layout, rounded up to the nearest block. This is equivalent to num_blocks * block_size.

Returns None if overflow occurs.

pub fn num_bytes_rounded_to_block_as_usize( &self, block_size: BlockSize, ) -> Option<usize>

Get the number of bytes needed for this layout, rounded up to the nearest block. This is equivalent to num_blocks * block_size.

Returns None if overflow occurs.

Trait Implementations

impl Clone for GptPartitionEntryArrayLayout

fn clone(&self) -> GptPartitionEntryArrayLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GptPartitionEntryArrayLayout

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

Formats the value using the given formatter.

impl Default for GptPartitionEntryArrayLayout

fn default() -> GptPartitionEntryArrayLayout

Returns the “default value” for a type.

impl Display for GptPartitionEntryArrayLayout

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

Formats the value using the given formatter.

impl Hash for GptPartitionEntryArrayLayout

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GptPartitionEntryArrayLayout

fn cmp(&self, other: &GptPartitionEntryArrayLayout) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for GptPartitionEntryArrayLayout

fn eq(&self, other: &GptPartitionEntryArrayLayout) -> 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 PartialOrd for GptPartitionEntryArrayLayout

fn partial_cmp(&self, other: &GptPartitionEntryArrayLayout) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
