Struct names should use PascalCase

Severity: Info ID: pascal-case-struct

Flags struct definitions whose names do not follow PascalCase.

What it does

Reports struct identifiers longer than one character that do not match the PascalCase convention. Single-character names are not checked.

Why is this bad?

The Solidity style guide recommends PascalCase for type-like names (contracts, structs, enums, libraries). Consistent casing makes code easier to scan and integrates with editor features and external tooling.

Example

Bad

solidity

struct user_info { uint256 balance; }
struct USERINFO   { uint256 balance; }

Good

solidity

struct UserInfo { uint256 balance; }
