Struct KzgSettings

#[repr(C)]
pub struct KzgSettings { /* private fields */ }

Stores the setup and parameters needed for computing KZG proofs.

Implementations

impl KZGSettings

Holds the parameters of a kzg trusted setup ceremony.

pub fn load_trusted_setup( g1_bytes: &[[u8; 48]], g2_bytes: &[[u8; 96]], ) -> Result<KZGSettings, Error>

Initializes a trusted setup from FIELD_ELEMENTS_PER_BLOB g1 points and 65 g2 points in byte format.

pub fn parse_kzg_trusted_setup( trusted_setup: &str, ) -> Result<KZGSettings, Error>

Parses the contents of a KZG trusted setup file into a KzgSettings.

pub fn load_trusted_setup_file(file_path: &CStr) -> Result<KZGSettings, Error>

Loads the trusted setup parameters from a file. The file format is as follows:

FIELD_ELEMENTS_PER_BLOB 65 # This is fixed and is used for providing multiproofs up to 64 field elements. FIELD_ELEMENT_PER_BLOB g1 byte values 65 g2 byte values

pub fn load_trusted_setup_file_inner( file_path: &CStr, ) -> Result<KZGSettings, Error>

Loads the trusted setup parameters from a file.

Same as load_trusted_setup_file , but takes a CStr instead of a Path .

Trait Implementations

impl Debug for KZGSettings

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

Formats the value using the given formatter.

impl Drop for KZGSettings

fn drop(&mut self)

Executes the destructor for this type.

impl Hash for KZGSettings

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 KZGSettings

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

impl Eq for KZGSettings

impl Send for KZGSettings

impl StructuralPartialEq for KZGSettings

impl Sync for KZGSettings

Safety: The memory for roots_of_unity and g1_values and g2_values are only freed on calling free_trusted_setup which only happens when we drop the struct.
