StorageSettingsFlags

reth_db::models::metadata

Struct StorageSettingsFlags 

pub struct StorageSettingsFlags { /* private fields */ }
Expand description

Fieldset that facilitates compacting the parent type. Used bytes: 1 | Unused bits: 7

Implementations§

§

impl StorageSettingsFlags

pub const fn new() -> StorageSettingsFlags

Returns an instance with zero initialized data.

§

impl StorageSettingsFlags

pub const fn into_bytes(self) -> [u8; 1]

Returns the underlying bits.

§Layout

The returned byte array is layed out in the same way as described here.

pub const fn from_bytes(bytes: [u8; 1]) -> StorageSettingsFlags

Converts the given bytes directly into the bitfield struct.

§

impl StorageSettingsFlags

pub fn storage_v2_len(&self) -> <B1 as Specifier>::InOut

Returns the value of storage_v2_len.

pub fn storage_v2_len_or_err( &self, ) -> Result<<B1 as Specifier>::InOut, InvalidBitPattern<<B1 as Specifier>::Bytes>>

Returns the value of storage_v2_len.

§Errors

If the returned value contains an invalid bit pattern for storage_v2_len.

pub fn with_storage_v2_len( self, new_val: <B1 as Specifier>::InOut, ) -> StorageSettingsFlags

Returns a copy of the bitfield with the value of storage_v2_len set to the given value.

§Panics

If the given value is out of bounds for storage_v2_len.

pub fn with_storage_v2_len_checked( self, new_val: <B1 as Specifier>::InOut, ) -> Result<StorageSettingsFlags, OutOfBounds>

Returns a copy of the bitfield with the value of storage_v2_len set to the given value.

§Errors

If the given value is out of bounds for storage_v2_len.

pub fn set_storage_v2_len(&mut self, new_val: <B1 as Specifier>::InOut)

Sets the value of storage_v2_len to the given value.

§Panics

If the given value is out of bounds for storage_v2_len.

pub fn set_storage_v2_len_checked( &mut self, new_val: <B1 as Specifier>::InOut, ) -> Result<(), OutOfBounds>

Sets the value of storage_v2_len to the given value.

§Errors

If the given value is out of bounds for storage_v2_len.

§

impl StorageSettingsFlags

pub fn from(buf: &[u8]) -> (StorageSettingsFlags, &[u8])

Deserializes this fieldset and returns it, alongside the original slice in an advanced position.
