pub struct PartitionTable {
    pub addr: u32,
    pub size: usize,
}

Partition table info

Fields

addr: u32

Address of table

size: usize

Size of table

Implementations

impl PartitionTable

pub const DEFAULT_ADDR: u32 = 32_768u32

Address of partition table

pub const MAX_SIZE: usize = 4_096usize

Maximum size of partition table

pub const MAX_ENTRIES: usize = 128usize

Maxumum number of partition entries

impl PartitionTable

pub fn new(addr: u32, size: usize) -> Self

Instantiate partition table with specified address and size

pub fn max_entries(&self) -> usize

Get maximum number of entries

impl PartitionTable

pub fn iter_storage<'s, S>( &self, storage: &'s mut S, calc_md5: bool, ) -> PartitionStorageIter<'s, S>

where S: ReadStorage,

Get iterator over partitions from table

If md5 feature isn’t enabled calc_md5 argument will be ignored.

pub fn read_storage<S, T>( &self, storage: &mut S, check_md5: Option<bool>, ) -> Result<T, StorageOpError<S>>

where S: ReadStorage, T: FromIterator<PartitionEntry>,

Read partitions from table

The check_md5 argument means following:

• None - ignore MD5 checksum
• Some(false) - check MD5 when found (optional MD5)
• Some(true) - MD5 checksum is mandatory

If md5 feature isn’t enabled check_md5 argument will be ignored.

pub fn write_storage<S>( &self, storage: &mut S, partitions: impl IntoIterator<Item = impl AsRef<PartitionEntry>>, write_md5: bool, ) -> Result<usize, StorageOpError<S>>

where S: Storage,

Write partitions into table

If md5 feature isn’t enabled write_md5 argument will be ignored.

impl PartitionTable

pub fn iter_nor_flash<'s, S>( &self, storage: &'s mut S, calc_md5: bool, ) -> PartitionNorFlashIter<'s, S>

where S: ReadNorFlash,

Get iterator over partitions from table

If md5 feature isn’t enabled calc_md5 argument will be ignored.

pub fn read_nor_flash<S, T>( &self, storage: &mut S, check_md5: Option<bool>, ) -> Result<T, NorFlashOpError<S>>

where S: ReadNorFlash, T: FromIterator<PartitionEntry>,

Read partitions from table

The check_md5 argument means following:

• None - ignore MD5 checksum
• Some(false) - check MD5 when found (optional MD5)
• Some(true) - MD5 checksum is mandatory

If md5 feature isn’t enabled check_md5 argument will be ignored.

pub fn write_nor_flash<S>( &self, storage: &mut S, partitions: impl IntoIterator<Item = impl AsRef<PartitionEntry>>, write_md5: bool, ) -> Result<usize, NorFlashOpError<S>>

where S: NorFlash,

Write partitions into table

If md5 feature isn’t enabled write_md5 argument will be ignored.

Trait Implementations

impl Clone for PartitionTable

fn clone(&self) -> PartitionTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionTable

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

Formats the value using the given formatter.

impl Default for PartitionTable

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PartitionTable

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