Struct TxScriptContext 

pub struct TxScriptContext {
    pub tx_index: usize,
    pub prevout_values_range: (usize, usize),
    pub script_pubkey_indices_range: (usize, usize),
    pub flags: u32,
    pub bip143: Option<Bip143PrecomputedHashes>,
    pub loop_idx: usize,
    pub fee: i64,
    pub ecdsa_index_base: usize,
    pub sighash_midstate_cache: Option<SighashMidstateCache>,
}

Per-tx context shared by all inputs of that tx. prevout_script_pubkeys and prevout_values in block-level buffers; context holds (start, count) ranges to avoid per-tx Vec allocations.

Fields

tx_index: usize

prevout_values_range: (usize, usize)

(start, count) range into BlockSessionContext.prevout_values_buffer

script_pubkey_indices_range: (usize, usize)

(start, count) range into BlockSessionContext.script_pubkey_indices_buffer

flags: u32

bip143: Option<Bip143PrecomputedHashes>

loop_idx: usize

fee: i64

ecdsa_index_base: usize

sighash_midstate_cache: Option<SighashMidstateCache>

Roadmap: Core-style (scriptCode, nHashType) -> hash cache. Helps multisig.
