Struct ScriptList 

pub struct ScriptList<'a> { /* private fields */ }

Parsed ScriptList table (chapter 2 §“ScriptList table”).

Layout:

  0 / 2 / scriptCount
  2 / 6 / scriptRecords[scriptCount]   // (tag[4] + scriptOffset[2])

The records are sorted alphabetically by tag, so Self::find runs a binary search.

Implementations

impl<'a> ScriptList<'a>

pub fn parse(bytes: &'a [u8]) -> Result<Self, Error>

Validate the header and the trailing scriptRecords[] array.

pub fn count(&self) -> u16

Number of ScriptRecords.

pub fn is_empty(&self) -> bool

true when the list is empty.

pub fn tag(&self, i: u16) -> Option<[u8; 4]>

Raw 4-byte tag at record index i, or None if out of range.

pub fn script(&self, i: u16) -> Option<Result<Script<'a>, Error>>

Parse the Script table referenced by record i. Returns None for an out-of-range index, an Err if the offset resolves outside the ScriptList or the Script header itself is truncated.

pub fn find(&self, tag: &[u8; 4]) -> Option<Result<Script<'a>, Error>>

Look up a Script by tag. Returns None when the tag is absent.

pub fn iter(&self) -> ScriptListIter<'a>

Iterate over (tag, script_result) pairs in on-disk order.

Trait Implementations

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

Performs copy-assignment from source.

impl<'a> Copy for ScriptList<'a>

impl<'a> Debug for ScriptList<'a>

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

Formats the value using the given formatter.
