Struct mycelium_kernel::arch::interrupt::SelectorErrorCode

pub struct SelectorErrorCode(/* private fields */);

Error code set by the “Invalid TSS”, “Segment Not Present”, “Stack-Segment Fault”, and “General Protection Fault” faults.

This includes a segment selector index, and includes 2 bits describing which table the segment selector references.

Implementations

impl SelectorErrorCode

pub const fn from_bits(bits: u16) -> SelectorErrorCode

Constructs a new instance of Self from the provided raw bits.

pub const fn new() -> SelectorErrorCode

Constructs a new instance of Self with all bits set to 0.

pub const fn bits(self) -> u16

Returns the raw bit representatiion of self as an integer.

pub fn with<T>( self, field: Pack16<T, SelectorErrorCode>, value: T ) -> SelectorErrorCode

where T: FromBits<u16>,

Packs the bit representation of value into self at the bit range designated by field, returning a new bitfield.

pub fn set<T>( &mut self, field: Pack16<T, SelectorErrorCode>, value: T ) -> &mut SelectorErrorCode

where T: FromBits<u16>,

Packs the bit representation of value into self at the range designated by field, mutating self in place.

pub fn get<T>(self, field: Pack16<T, SelectorErrorCode>) -> T

where T: FromBits<u16>,

Unpacks the bit range represented by field from self, and converts it into a T-typed value.

Panics

This method panics if self does not contain a valid bit pattern for a T-typed value, as determined by T’s FromBits::try_from_bits implementation.

pub fn try_get<T>( self, field: Pack16<T, SelectorErrorCode> ) -> Result<T, <T as FromBits<u16>>::Error>

where T: FromBits<u16>,

Unpacks the bit range represented by field from self and attempts to convert it into a T-typed value.

Returns

• Ok(T) if a T-typed value could be constructed from the bits in src
• Err(T::Error) if src does not contain a valid bit pattern for a T-typed value, as determined by T’s [FromBits::try_from_bits implementation.

pub fn assert_valid()

Asserts that all the packing specs for this type are valid.

This is intended to be used in unit tests.

pub fn display_ascii(&self) -> impl Display

Returns a value that formats this bitfield in a multi-line format, using only ASCII characters.

This is equivalent to formatting this bitfield using a {} display specifier, but will never use Unicode box-drawing characters, even when an upstream formatter uses the {:#} fmt::Display specifier. This is intended for use on platforms where Unicode box drawing characters are never available.

pub fn display_unicode(&self) -> impl Display

Returns a value that formats this bitfield in a multi-line format, always using Unicode box-drawing characters.

This is equivalent to formatting this bitfield using a {:#} format specifier, but will always use Unicode box-drawing characters, even when an upstream formatter uses the {} fmt::Display specifier.
