Enum ResourceData

pub enum ResourceData {
    File(PathBuf),
    Buffer(Vec<u8>),
    ArchiveOffset {
        offset: u32,
        size: u32,
    },
}

ERF resource data source

Variants

File(PathBuf)

The resource data is located in a separate file

Buffer(Vec<u8>)

The resource data is located here in a buffer

ArchiveOffset

The resource data is located in the ERF file and is not available because the ERF file has not been loaded in memory

Fields

offset: u32

size: u32

Implementations

impl ResourceData

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

Returns the length of the resource in bytes. None if it is unknown

pub fn is_empty(&self) -> Option<bool>

pub fn file_read(&self) -> Result<Vec<u8>, Error>

Read the file of a ResourceData::File and returns its data

Panics

If self is not a ResourceData::File

pub fn file_load(&mut self) -> Result<(), Error>

Converts a ResourceData::File into a ResourceData::Buffer by loading the file content in memory

Panics

If self is not a ResourceData::File

pub fn archiveoffset_seek( &self, stream: &mut (impl Seek + Read), ) -> Result<Vec<u8>, Error>

Seeks and returns the data pointed by the ResourceData::ArchiveOffset

This is typically used to fetch a resource data when only the head of the ERF file has been parsed

Panics

If self is not a ResourceData::ArchiveOffset

pub fn archiveoffset_load_stream( &mut self, stream: &mut (impl Seek + Read), ) -> Result<(), Error>

Converts a ResourceData::ArchiveOffset into a ResourceData::Buffer by loading the file content in memory

Panics

If self is not a ResourceData::ArchiveOffset

pub fn archiveoffset_load( &mut self, buffer: &[u8], buffer_offset: u32, ) -> Result<(), String>

Converts a ResourceData::ArchiveOffset into a ResourceData::Buffer by referencing data from buffer

Args:

• buffer: bytes buffer containing the archive data
• buffer_offset: offset if the buffer has been truncated

Panics

If self is not a ResourceData::ArchiveOffset

Trait Implementations

impl Debug for ResourceData

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

Formats the value using the given formatter.
