i'm trying extend grid struct piston-2dgraphics library. there's no method getting location on window of particular cell, implemented trait calculate me. then, wanted method calculate neighbours of particular cell on grid, implemented trait. something ugly , feels unnecessary seeing how i'll never use these traits other specific grid structure. so, there way in rust extend struct without having implement traits each time? as of rust 1.3, no, there no other way. it's not possible define inherent methods on type defined in crate. however, know, can define own trait methods need, implement trait external type. pattern known extension traits . name of extension traits, convention, ends ext , indicate trait not meant used generic bound or trait object. there few examples in standard library. other libraries can export extension traits (example: byteorder ). however, other trait, need bring trait's methods in scope use somethingext; .

javascript - Best way to test global npm modules -

lets develop global npm module called mytool registers env variable through "bin" in package.json name mytool . so after install globally typing npm install mytool -g then can type mytool --someoption in terminal , handle cli input in javascript. lets assume mytool works lot current working directory of cli, just node index.js --someoption is bad idea. however test bugs don't want push new version of "mytool" npm , install globally npm. rather want able test locally. question: best way test global npm modules without publishing npm? npm link contrary seems, npm link can used in case, too. using in package folder " will create symlink in global folder {prefix}/lib/node_modules/&lt;package&gt; links package npm link command executed.
