Struct ContextDescriptor 

pub struct ContextDescriptor {
    pub name: &'static str,
    pub accounts: &'static [ContextAccountDescriptor],
    pub policies: &'static [&'static str],
    pub receipts_expected: bool,
    pub mutation_classes: &'static [&'static str],
}

Schema descriptor for an entire instruction context (account struct).

Captures the full Account DSL metadata for a single instruction’s account requirements. Used for explain output, schema comparison, and manifest inclusion.

Fields

name: &'static str

Context struct name (e.g. “Deposit”, “Withdraw”).

accounts: &'static [ContextAccountDescriptor]

Per-account field descriptors.

policies: &'static [&'static str]

Policy pack names used by this context.

receipts_expected: bool

Whether receipts are expected from this instruction.

mutation_classes: &'static [&'static str]

Mutation class names (e.g. “Financial”, “InPlace”).
