Struct LoadMask 

pub struct LoadMask {
    pub quality_lo: u8,
    pub quality_hi: u8,
}

plLoadMask — determines whether an object should be loaded based on quality and capability settings.

Fields

quality_lo: u8

Quality mask for capability level 0 (low-end hardware).

quality_hi: u8

Quality mask for capability level 1 (high-end hardware).

Implementations

impl LoadMask

pub const ALWAYS: LoadMask

pub const NEVER: LoadMask

pub fn from_byte(byte: u8) -> Self

Create from packed byte (same encoding as PRP file).

pub fn new(quality_lo: u8, quality_hi: u8) -> Self

pub fn from_packed(byte: u8) -> Self

Construct from the packed single-byte serialization format. C++ ref: plLoadMask::Read (CoreLib/plLoadMask.cpp:81-92)

pub fn is_used(&self) -> bool

Returns true if this mask actually filters (is not “always load”).

pub fn never_loads(&self) -> bool

Returns true if this mask would never load anything.

pub fn read(reader: &mut impl Read) -> Result<Self>

Read from stream: 1 packed byte. Upper nibble = quality[0] lower 4 bits, lower nibble = quality[1] lower 4 bits. On read, OR in 0xF0 to reconstruct full byte.

pub fn write(&self, writer: &mut impl Write) -> Result<()>

Write to stream: 1 packed byte.

Trait Implementations

impl Clone for LoadMask

fn clone(&self) -> LoadMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoadMask

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

Formats the value using the given formatter.

impl Default for LoadMask

fn default() -> Self

Returns the “default value” for a type.

impl Hash for LoadMask

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 PartialEq for LoadMask

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