eth::cli¶

Classes¶

	Name
struct	eth::cli::WatchSpec One watch subscription specified on the command line.
class	eth::cli::EventRegistry Registry mapping event signatures to their ABI parameter descriptors.

Functions¶

	Name
std::optional< uint8_t >	hex_nibble(char c) Parse a hex nibble character. Returns nullopt for invalid chars.
template <size_t N> bool	parse_hex_array(std::string_view hex, std::array< uint8_t, N > & out) Parse a hex string into a fixed-size byte array.
std::optional< codec::Address >	parse_address(std::string_view hex) Parse a 0x-prefixed or bare 40-hex-char Ethereum address.
EventRegistry &	event_registry() Process-wide singleton registry, pre-populated with well-known events.
std::vector< abi::AbiParam >	infer_params(const std::string & sig) Convenience wrapper: look up `sig` in the global registry. Replaces the old `infer_params()` free function.

Functions Documentation¶

function hex_nibble¶

inline std::optional< uint8_t > hex_nibble(
    char c
)

Parse a hex nibble character. Returns nullopt for invalid chars.

function parse_hex_array¶

template <size_t N>
bool parse_hex_array(
    std::string_view hex,
    std::array< uint8_t, N > & out
)

Parse a hex string into a fixed-size byte array.

Parameters:

hex Must be exactly N*2 hex characters (no 0x prefix).

function parse_address¶

inline std::optional< codec::Address > parse_address(
    std::string_view hex
)

Parse a 0x-prefixed or bare 40-hex-char Ethereum address.

Return: Parsed address or nullopt if the format is invalid.

function event_registry¶

inline EventRegistry & event_registry()

Process-wide singleton registry, pre-populated with well-known events.

The registry is initialised on first access. All registrations persist for the lifetime of the process, so call register_event() once at startup before creating any watchers.

function infer_params¶

inline std::vector< abi::AbiParam > infer_params(
    const std::string & sig
)

Convenience wrapper: look up sig in the global registry. Replaces the old infer_params() free function.
